The title complex, [Cu(C6H4N3)]n, was synthesized by the reaction of cupric nitrate, 1H-benzotriazole (BTAH) and aqueous ammonia under hydrothermal conditions. The asymmetric unit contains three crystallographically independent CuIcations and two 1H-benzotriazolate ligands. Two of the CuIcations, one with a linear two-coordinated geometry and one with a four-coordinated tetrahedral geometry, are located on sites with crystallographically imposed twofold symmetry. The third CuIcation, with a planar three-coordinated geometry, is on a general position. Two CuIcations are doubly bridged by two BTA−ligands to afford a noncentrosymmetric planar [Cu2(BTA)2] subunit, and two [Cu2(BTA)2] subunits are arranged in an antiparallel manner to form a centrosymmetric [Cu2(BTA)2]2secondary building unit (SBU). The SBUs are connected in a crosswise mannerviathe sharing of four-coordinated CuIcations, Cu—N bonding and bridging by two-coordinate CuIcations, resulting in a one-dimensional chain along thecaxis. These one-dimensional chains are further linked by C—H...π and weak van der Waals interactions to form a three-dimensional supramolecular architecture.

A novel infinite one-dimensional silver cylinder, namely poly[μ-ethylenediamine-μ5-(2-sulfanidylbenzoato)-μ4-(2-sulfanidylbenzoato)-tetrasilver(I)], [Ag4(C7H4O2S)2(C2H8N2)]n, has been synthesized by one-pot reaction of equivalent molar silver nitrate and 2-mercaptobenzoic acid (H2mba) in the presence of ethylenediamine (eda). One Ag atom is located in an AgS2NO four-coordinated tetrahedral geometry, two other Ag atoms are in an AgS2O three-coordinated T-shaped geometry and the fourth Ag atom is in an AgSNO coordination environment. The two mba ligands show two different binding modes. The μ2-N:N′-eda ligand, acting as a bridge, combines with mba ligands to extend the AgIions into a one-dimensional silver cylinder incorporating abundant Ag...Ag interactions ranging from 2.9298 (11) to 3.2165 (13) Å. Interchain N—H...O hydrogen bonds extend the one-dimensional cylinder into an undulating two-dimensional sheet, which is further packed into a three-dimensional supramolecular framework by van der Waals interactions; no π–π interactions were observed in the crystal structure.

The asymmetric unit of the title coordination polymer, [Co(C9H4N2O4)(C2H4N4)] n or [Co(L 1)(L 2)] n , consists of one crystallographically independent Co2+ centre, one L 1 2− ligand and one L 2 ligand (L 1 = 1H-benzimidazole-5,6-dicarboxylic acid, L 2 = 3-amino-1,2,4-triazole). The Co2+ centre is coordinated by two carboxylato-O atoms from two independent L 1 2− ligands and two nitrogen atoms from L 2 and another L 1 ligand. Thus, the metal center adopts a four-coordinate mode, forming a tetrahedral geometry. Interestingly, through the combination of two L 1 2−, two L 2 ligands and two Co2+ ions, a basic repeating unit is constructed, resulting in the formation of a one-dimensional straight chain structure. These chains are further expanded to the final three-dimensional framework via N—H...O hydrogen-bonding interactions.

The reaction of mercury(II) chloride with bis(pyridin-3-ylmethyl)sulfane (L, C12H12N2S) in methanol afforded the title crystalline coordination polymercatena-poly[[dichloridomercury(II)]-μ-bis(pyridin-3-ylmethyl)sulfane-κ2N:N′], [HgCl2L]n. The asymmetric unit consists of one HgIIcation, oneLligand and two chloride anions. Each HgIIion is coordinated by two pyridine N atoms from separateLligands and two chloride anions. The metal adopts a highly distorted tetrahedral geometry, with bond angles about the central atom in the range 97.69 (12)–153.86 (7)°. EachLligand bridges two HgIIions, forming an infinite –(Hg–L)n– zigzag chain along thebaxis, with an Hg...Hg separation of 10.3997 (8) Å. In the crystal, adjacent chains are connected by intermolecular C—H...Cl hydrogen bonds, together with Hg—Cl...π interactions [chloride-to-centroid distance = 3.902 (3) Å], that form between a chloride anion and the one of the pyridine rings ofL, generating a two-dimensional layer extending parallel to (101). These layers are further linked by intermolecular C—H...π hydrogen bonds, forming a three-dimensional supramolecular network.

Two alkaline earth–tetrazole compounds, namelycatena-poly[[[triaquamagnesium(II)]-μ-5,5′-(azanediyl)ditetrazolato-κ3N1,N1′:N5] hemi{bis[μ-5,5′-(azanediyl)ditetrazolato-κ3N1,N1′:N2]bis[triaquamagnesium(II)]} monohydrate], {[Mg(C2HN9)(H2O)3][Mg2(C2HN9)2(H2O)6]0.5·H2O}n, (I), and bis[5-(pyrazin-2-yl)tetrazolate] hexaaquamagnesium(II), (C5H3N6)[Mg(H2O)6], (II), have been prepared under hydrothermal conditions. Compound (I) is a mixed dimer–polymer based on magnesium ion centres and can be regarded as the first example of a magnesium–tetrazolate polymer in the crystalline form. The structure shows a complex three-dimensional hydrogen-bonded network that involves magnesium–tetrazolate dimers, solvent water molecules and one-dimensional magnesium–tetrazolate polymeric chains. The intrinsic cohesion in the polymer chains is ensured by N—H...N hydrogen bonds, which formR22(7) rings, thus reinforcing the propagation of the polymer chain along theaaxis. The crystal structure of magnesium tetrazole salt (II) reveals a mixed ribbon of hydrogen-bonded rings, of typesR22(7),R22(9) andR24(10), running along thecaxis, which are linked byR24(16) rings, generating a 4,8-cflunet.

The title compound, {[Co(H2O)6][Co(SO4)(C10H8N2)(H2O)3][Co(SO4)2(C10H8N2)(H2O)2]}n, contains three crystallographically unique CoIIcentres, all of which are in six-coordinated environments. One CoIIcentre is coordinated by two bridging 4,4′-bipyridine (4,4′-bipy) ligands, one sulfate ion and three aqua ligands. The second CoIIcentre is surrounded by two N atoms of two 4,4′-bipy ligands and four O atoms,i.e.two O atoms from two monodentate sulfate ions and two from water molecules. The third CoIIcentre forms part of a hexaaquacobalt(II) ion. In the crystal structure, there are two different one-dimensional chains, one being anionic and the other neutral, and adjacent chains are arranged in a cross-like fashion around the mid-point of the 4,4′-bipy ligands. The structure features O—H...O hydrogen-bonding interactions between sulfate anions and water molecules, resulting in a three-dimensional supramolecular network.

Each metal ion exhibits a distorted tetrahedral coordination geometry consisting of two pyridyl and two benzimidazole N atoms from four distinct ligands. Two metal ions are linked by two bep ligands to form a centrosymmetric 18-memberedM2(bep)2metallacycle, while adjacentM2(bep)2metallacycles are further interlinked by another two bep ligands resulting in a ladder-like array. In the extended structure, four adjacent ladder-like arrays are connected together through C—H...F, O—H...O and C—H...O hydrogen bonds between bep ligands, solvent molecules and counter-anions into a three-dimensional supramolecular structure.

The title ZnIIcomplex, [Zn(C18H18N3S)2], (I), features two independent but chemically equivalent molecules in the asymmetric unit. In each, the thiosemicarbazonate monoanion coordinates the ZnIIatomviathe thiolate-S and imine-N atoms, with the resulting N2S2donor set defining a distorted tetrahedral geometry. The five-membered ZnSCN2chelate rings adopt distinct conformations in each independent molecule,i.e.one ring is almost planar while the other is twisted about the Zn—S bond. In the crystal, the two molecules comprising the asymmetric unit are linked by amine-N—H...N(imine) and amine-N—H...S(thiolate) hydrogen bondsviaan eight-membered heterosynthon, {...HNCN...HNCS}. The dimeric aggregates are further consolidated by benzene-C—H...S(thiolate) interactions and are linked into a zigzag supramolecular chain along thecaxisviaamine-N—H...S(thiolate) hydrogen bonds. The chains are connected into a three-dimensional architectureviaphenyl-C—H...π(phenyl) and π–π interactions, the latter occurring between chelate and phenyl rings [inter-centroid separation = 3.6873 (11) Å]. The analysis of the Hirshfeld surfaces calculated for (I) emphasizes the different interactions formed by the independent molecules in the crystal and the impact of the π–π interactions between chelate and phenyl rings.

A homochiral helical three-dimensional coordination polymer, poly[[(μ2-acetato-κ3O,O′:O)(hydroxido-κO)(μ4-5-nicotinamido-1H-1,2,3,4-tetrazol-1-ido-κ5N1,O:N2:N4:N5)(μ3-5-nicotinamido-1H-1,2,3,4-tetrazol-1-ido-κ4N1,O:N2:N4:N5)dicadmium(II)] 0.75-hydrate], {[Cd2(C7H5N6O)2(CH3COO)(OH)]·0.75H2O}n, was synthesized by the reaction of cadmium acetate,N-(1H-tetrazol-5-yl)isonicotinamide (H-NTIA), ethanol and H2O under hydrothermal conditions. The asymmetric unit contains two crystallographically independent CdIIcations, two deprotonated 5-nicotinamido-1H-1,2,3,4-tetrazol-1-ide (NTIA−) ligands, one acetate anion, one hydroxide anion and three independent partially occupied water sites. The two CdIIcations, with six-coordinated octahedral and seven-coordinated pentagonal bipyramidal geometries are located on general sites. The tetrazole group of one symmetry-independent NTIA−ligand links one of the independent CdIIcations into 61helical chains, while the other NTIA−ligand links the other independent CdIIcations into similar but unequal 61helical chains. These chains, with a pitch of 24.937 (5) Å, intertwine into a double-stranded helix. Each of the double-stranded 61helices is further connected to six adjacent helical chains through an acetate μ2-O atom and the tetrazole group of the NTIA−ligand into a three-dimensional framework. The helical channel is occupied by the isonicotinamide groups of NTIA−ligands and two helices are connected to each other through the pyridine N and carbonyl O atoms of isonicotinamide groups. In addition, N—H...O and O—H...N hydrogen bonds exist in the complex.

A novel three-dimensional ZnII complex, poly[[(μ2-4,4′-bipyridine)(μ4-naphthalene-1,4-dicarboxylato)(μ2-naphthalene-1,4-dicarboxylato)dizinc(II)] dimethylformamide monosolvate monohydrate], {[Zn2(C12H6O4)2(C10H8N2)]·2C3H7NO·H2O)} n , has been prepared by the solvothermal assembly of Zn(NO3)·6H2O, naphthalene-1,4-dicarboxylic acid and 4,4′-bipyridine. The two crystallographically independent Zn atoms adopt the same four-coordinated tetrahedral geometry (ZnO3N) by bonding to three O atoms from three different naphthalene-1,4-dicarboxylate (1,4-ndc) ligands and one N atom from a 4,4′-bipyridine (bpy) ligand. The supramolecular secondary building unit (SBU) is a distorted paddle-wheel-like {Zn2(COO)2N2O2} unit and these units are linked by 1,4-ndc ligands within the layer to form a two-dimensional net parallel to the ab plane, which is further connected by bpy ligands to form the three-dimensional framework. The single net leaves voids that are filled by mutual interpenetration of an independent equivalent framework in a twofold interpenetrating architecture. The title compound is stable up to 673 K. Excitation and luminescence data observed at room temperature show that it emits bright-blue fluorescence.
