Two new ZnIIcoordination polymers, namely,catena-poly[[dibromidozinc(II)]-μ-[3,6-bis(pyridin-4-yl)phenanthrene-9,10-dione-κ2N:N′]], [ZnBr2(C24H14N2O2)]n, (1), and poly[[bromido[μ3-10-hydroxy-3,6-bis(pyridin-4-yl)phenanthren-9-olato-κ3N:N′:O9]zinc(II)] hemihydrate], {[ZnBr(C24H15N2O2)]·0.5H2O}n, (2), have been synthesized through hydrothermal reaction of ZnBr2and a 60° angular phenanthrenedione-based linker,i.e.3,6-bis(pyridin-4-yl)phenanthrene-9,10-dione, in different solvent systems. Single-crystal analysis reveals that polymer (1) features one-dimensional zigzag chains connected by weak C—H...π and π–π interactions to form a two-dimensional network. The two-dimensional networks are further stacked in anABABfashion along theaaxis through C—H...O hydrogen bonds. LayersAandBcomprise left- and right-handed helical chains, respectively. Coordination polymer (2) displays a wave-like two-dimensional layered structure with helical chains. In this compound, there are two opposite helical –Zn–HL– chains [HLis 10-hydroxy-3,6-bis(pyridin-4-yl)phenanthren-9-olate] in adjacent layers. The layers are packed in anABABsequence and are further connected through O—H...Br and O—H...O hydrogen-bond interactions to form a three-dimensional framework. In (1) and (2), the mutidentateLand HLligands exhibits different coordination modes.

Two cadmium halide complexes,catena-poly[[chloridocadmium(II)]-di-μ-chlorido-[chloridocadmium(II)]-bis[μ2-4-(dimethylamino)pyridin-1-ium-1-acetate]-κ3O:O,O′;κ3O,O′:O], [CdCl2(C9H12N2O2)]n, (I), andcatena-poly[1-cyanomethyl-1,4-diazoniabicyclo[2.2.2]octane [[dichloridocadmium(II)]-μ-oxalato-κ4O1,O2:O1′,O2′] monohydrate], {(C8H15N3)[CdCl2(C2O4)]·H2O}n, (II), were synthesized in aqueous solution. In (I), the CdIIcation is octahedrally coordinated by three O atoms from two carboxylate groups and by one terminal and two bridging chloride ligands. Neighbouring CdIIcations are linked together by chloride anions and bridging O atoms to form a one-dimensional zigzag chain. Hydrogen-bond interactions are involved in the formation of the two-dimensional network. In (II), each CdIIcation is octahedrally coordinated by four O atoms from two oxalic acid ligands and two terminal Cl−ligands. Neighbouring CdIIcations are linked together by oxalate groups to form a one-dimensional anionic chain, and the water molecules and organic cations are connected to this one-dimensional zigzag chain through hydrogen-bond interactions.

In the title compound, C9H9N3OS, the plane of the benzene ring forms a dihedral angle of 33.40 (5)° with that of the triazole group. In the crystal, molecules are linked by O—H...N hydrogen bonds involving the phenol –OH group and one of the unsubstituted N atoms of the triazole ring, resulting in chains along [010]. These chains are further extended into a layer parallel to (001) by weak C—H...N hydrogen-bond interactions. Aromatic π–π stacking [centroid–centroid separation = 3.556 (1) Å] between the triazole rings links the layers into a three-dimensional network.

In the title compound, [Cu2(C7H4O5S)2(C12H8N2)2(H2O)2]·3H2O, each copper(II) atom is coordinated by two N atoms from one 1,10-phenanthroline molecule, two carboxylate O atoms from two 2-sulfonatobenzoato dianions and one aqua O atom in a distorted square pyramidal geometry. The 2-sulfonatobenzoato dianions function as μ2-bridging ligands in the formation of a dinuclear complex. Intermolecular hydrogen-bond interactions link the dinuclear units into a two-dimensional network structure.

Single-crystal X-ray diffraction analysis of poly[bis(μ2-5-carboxy-2-propyl-1H-imidazole-4-carboxylato-κ3N3,O4:O5)copper(II)], [Cu(C8H9N2O4)2)]n, indicates that one carboxylic acid group of the 2-propyl-1H-imidazole-4,5-dicarboxylic acid (H3PDI) ligand is deprotonated. The resulting H2PDI−anion, acting as a bridge, connects the CuIIcations to form a two-dimensional (4,4)-connected layer. Adjacent layers are further linked through interlayer hydrogen-bond interactions, resulting in a three-dimensional supramolecular structure.

Butanedioic Acid

The crystal structures of two urea–dicarboxylic acid (2:1) cocrystals have been determined. Urea–butanedioic acid forms monoclinic crystals, space group P21/c (No. 14), with a = 5.637 (4), b = 8.243 (3), c = 12.258 (3) Å, β = 96.80 (5)°, V = 565.6 (8) Å3, Z = 2. Urea–E-butenedioic acid also forms monoclinic crystals, space group P21/c (No. 14), with a = 5.540 (1), b = 8.227 (1), c = 12.426 (3) Å, β = 97.22 (3)°, V = 561.9 (2) Å3, Z = 2. The geometry and the conformation of both molecular aggregates and the three-dimensional networks formed are very similar. The two strongest hydrogen-bond interactions are constrained in the formation of the heteroaggregates, the third hydrogen-bond interaction is used to self-associate the heteroaggregates in one-dimensional chains, whereas the next three weaker hydrogen bonds interconnect the chains into well organized three-dimensional networks.

Strong Antiferromagnetic Interaction

The X-ray structure, porous and magnetic property of a self-assembled network 1 is described in detail. The single crystal X-ray analysis provides 1 as a three-dimensional network, which contains two-dimensional permanent ring forming nanoscale one-dimensional channels. The inter-replacement of perchlorate and hexafluorophosphate anions in solid 1 proves its porous structure. There is somewhat strong antiferromagnetic interaction (J = −74.1 cm−1) between two copper(II) ions through oxalate bridge and weak antiferromagnetic interaction (J = −5.1 cm−1) through AEP ligand.

To explore the effect of the nature of substitutions on the structural parameters and hydrogen-bond interactions inN-acylhydrazone derivatives, the crystal structures of threeortho-substitutedN-acylhydrazone derivatives, namely (E)-N-{2-[2-(2-chlorobenzylidene)hydrazinyl]-2-oxoethyl}-4-methylbenzenesulfonamide, C16H16ClN3O3S (I), (E)-N-{2-[2-(2-methylbenzylidene)hydrazinyl]-2-oxoethyl}-4-methylbenzenesulfonamide, C17H19N3O3S (II), and (E)-N-{2-[2-(2-nitrobenzylidene)hydrazinyl]-2-oxoethyl}-4-methylbenzenesulfonamide, C16H16N4O5S (III), have been determined. The structures of the three compounds display similar molecular conformations and hydrogen-bond patterns. The hydrazone part of the molecule, C—C—N—N=C, is almost planar in all the compounds, with the C—C—N—N and C—N—N=C torsion angles being 179.5 (3) and 177.1 (3)°, respectively, in (I), −179.4 (2) and −177.1 (3)° in (II) and −179.7 (2) and 173.4 (2)° in (III). The two phenyl rings on either side of the chain are approximately parallel to each other. In the crystal, the molecules are linked to each otherviaN—H...O hydrogen bonds, forming ribbons withR22(8) andR22(10) ring motifs. The introduction of electron-withdrawing groups (by a chloro or nitro group) to produce compounds (I) or (III) results in C—H...O hydrogen-bonding interactions involving the sulfonyl O atoms of adjacent ribbons, forming layers parallel to theabplane in (I) or a three-dimensional network in (III). In (III), one O atom of the nitro group is disordered over two orientations with refined occupancy ratio of 0.836 (12):0.164 (12).

In the title compound, [PdCl2(C21H23N3O)2], the PdIIatom is located on an inversion centre and is coordinated in a slightly distorted square-planar environment by the chloride andN-heterocyclic carbene (NHC) ligands in mutualtranspositions. There are several hydrogen-bonding interactions, the most significant of which is a hydrogen bond between the amide moiety of the NHC and the chloride ligand. These hydrogen-bond interactions form a three-dimensional network.
