In the title one-dimensional coordination polymer, [Cu(SiF6)(C3H4N2)4]n, the CuIIatom is coordinated by two hexafluoridosilicate F atoms and four pyrazole N atoms in a distortedtrans-CuF2N4octahedral environment. The dihedral angle between the planes of the pyrazlole rings in the asymmetric unit is 74.4 (3)°. The hexafluoridosilicate dianion acts as a bridging ligand, connecting the CuIIatoms into a [1-10] chain. The Cu and Si atoms lie on special positions with 2/msite symmetry. In the crystal, intrachain N—H...F hydrogen bonds occur and weak C—H...F interactions link the chains.

In the title one-dimensional ZnIIcoordination polymer, [Zn(C10H8O4)0.5Cl(C12H12N6)]n, the asymmetric unit consists of a ZnIIcation, a 1,3-bis[(1H-1,2,4-triazol-1-yl)methyl]benzene ligand and half of a fully deprotonated centrosymmetric 1,4-phenylenediacetic acid ligand. The crystal structure shows a one-dimensional rotaxane-like structure. This coordination polymer is reinforced by C—H...O and C—H...Cl hydrogen bonds and π–π interactions.

In the title compound, [Cu(C2N3)2(C12H10N6)]nor [Cu(dca)2(abpt)]n, where abpt is 4-amino-3,5-bis(pyridin-2-yl)-4H-1,2,4-triazole and dca is the dicyanamide anion, the CuIIcentre is five-coordinate with an approximately square-pyramidal geometry. One of the two dicyanamide ligands is a terminal ligand, but the other one acts as a μ1,5-bridging ligand between pairs of CuIIcentres, so generating a one-dimensional coordination polymer. A combination of N—H...N and C—H...N hydrogen bonds, augmented by π–π stacking interactions, links the coordination polymer chains into a bilayer structure. Comparisons are made with some related CuIIcomplexes containing dca ligands and heteroaromatic co-ligands.

In the title one-dimensional coordination polymer, {[ZnCl2(C18H14N4)]·0.25H2O}n, the ZnIIatom is coordinated by two chloride ions and two 4,4′-bis(1H-imidazol-1-yl)biphenyl ligands, generating a distorted tetrahedral ZnCl2N2geometry. The dihedral angle between the benzene rings of the ligand is 51.0 (1)° and the dihedral angles between the benzene rings and their attached imidazole rings are 18.7 (2) and 45.9 (1)°. The bridging ligand leads to [10-1] polymeric chains in the crystal and the disordered water molecule (occupancy 0.25) forms O—H...Cl hydrogen bonds.

In the title one-dimensional coordination polymer, [Mn(NCS)3(C10H16N3)]n, the MnIIatom is coordinated by anN,N′-bidentate Schiff base and four thiocyanate ligands in a distorted octahedral N5S geometry. Bridging thiocyanate ligands interconnect adjacent [Mn(NCS)2(C10H16N3)] units, giving rise to helical chains extending along thebaxis. The chains are further linked through N—H...S hydrogen bonds, leading to a three-dimensional supramolecular network.

The rigid organic ligand (pyridine-3,5-diyl)diphosphonic acid has been used to create the title novel three-dimensional coordination polymer, [Ca(C5H6NO6P2)2(H2O)]n. The six-coordinate calcium ion is in a distorted octahedral environment, formed by five phosphonate O atoms from five different (pyridin-1-ium-3,5-diyl)diphosphonate ligands, two of which are unique, and one water O atom. Two crystallographically independent acid monoanions,L1 andL2, serve to link metal centres using two different coordination modes,viz.η2μ2and η3μ3, respectively. The latter ligand,L2, forms a strongly undulated two-dimensional framework parallel to the crystallographicbcplane, whereas the former ligand,L1, is utilized in the formation of one-dimensional helical chains in the [010] direction. The two sublattices ofL1 andL2 interweave at the Ca2+ions to form a three-dimensional framework. In addition, multiple O—H...O and N—H...O hydrogen bonds stabilize the three-dimensional coordination network. Topologically, the three-dimensional framework can be simplified as a very unusual (2,3,5)-connected three-nodal net represented by the Schläfli symbol (4·82)(4·88·10)(8).

In the title one-dimensional coordination polymer, [Sn(CH3)3(C8H6NO4)]n, the SnIVatom is coordinated by three methyl C atoms and two carboxylate O atoms (one symmetry generated), resulting in an almost regular SnC3O2trigonal pyramid. The C atoms occupy the equatorial sites and the O atoms occupy the axial sites. In the ligand, the dihedral angles between the benzene ring and the pendant acetate and nitro groups are 57.7 (1) and 36.9 (3)°, respectively. The bridging ligand leads to [010] chains in the crystal, with adjacent metal atoms related by a 21screw axis. A weak π–π interaction exists between the centroids of symmetry-related benzene rings at a distance of 3.9131 (19) Å.

The asymmetric unit consists of a {Ba[Co(H–2L1)](ClO4)(H2O)}+cationic fragment and a non-coordinating ClO4−anion. In the neutral [Co(H–2L1)] moiety, the cobalt ion is hexacoordinated in a trigonal–prismatic fashion by the surrounding N4O2donor set. The Ba2+ion is nine-coordinated and exhibits a distorted [BaO9] monocapped square-antiprismatic geometry, the six oxygen atoms coming from three distinct [Co(H–2L1)] moieties, while the remaining three vertices are occupied by the oxygen atoms of a bidentate perchlorate anion and a water molecule. A barium–μ2-oxygen motif develops along theaaxis, connecting symmetry-related dinuclear BaII–CoIIcationic fragments in a wave-like chain, forming a one-dimensional metal coordination polymer. Non-coordinating ClO4−anions are located in the space between the chains. Weak C—H...O hydrogen bonds involving both coordinating and non-coordinating perchlorate anions build the whole crystal architecture. To our knowledge, this is the first example of a macrocyclic ligand forming a BaII-based one-dimensional coordination polymer, containing CoIIions surrounded by a N4O2donor set.

The title compound, C14H12INO3S, crystallizes with two independent molecules (AandB) in the asymmetric unit. The dihedral angle between the two aryl rings is 83.1 (4)° in moleculeAand 79.8 (4)° in moleculeB. In the crystal, the two molecules are linked by a pair of N—H...O hydrogen bonds, forming anA–Bdimer with anR22(8) ring motif. The dimer is further strengthened by a pair of C—H...O hydrogen bonds with anR22(14) motif. Another pair of C—H...O interactions assembles these dimers along the diagonal of thebcplane, forming ribbons. Adjacent ribbons are connected by C—H...πarylinteractions between theAmolecules, and thus the overall supramolecular architecture is one-dimensional.

Compounds (I) and (II) are closely related one-dimensional polymers based on 16- and 20-membered macrocycles along the chains, but they are not isomorphous. The chains are crosslinked into a two-dimensional networkviahydrogen bonds and π–π interactions in (I), and into a three-dimensional framework through π–π interactions in (II). One well-ordered solvent water molecule per asymmetric unit is included in (I) and forms O...Br hydrogen bonds.
