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, [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.

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 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.

Title One

The asymmetric unit of the title one-dimensional polymeric compound, {[Co(C10H11O2)2(H2O)3]·2H2O}n, contains one CoIIcation situated on a centre of inversion, one-half of a coordinating water molecule, one 2,4,6-trimethylbenzoate (TMB) anion together with one coordinating and one non-coordinating water molecule; the TMB anion acts as a monodentate ligand. In the anion, the carboxylate group is twisted away from the attached benzene ring by 84.9 (2)°. The CoIIatom is coordinated by two TMB anions and two water molecules in the basal plane, while another water molecule bridges the CoIIatoms in the axial directions, forming polymeric chains running along [001]. The coordination environment for the CoIIcation is a slightly distorted octahedron. The coordinating and bridging water molecules link to the carboxylate groupsviaintra- and intermolecular O—H...O hydrogen bonds, enclosingS(6) ring motifs, while the coordinating, bridging and non-coordinating water molecules link to the carboxylate groups and the coordinating water molecules link to the non-coordinating water moleculesviaO—H...O hydrogen bonds, enclosingR22(8) andR33(8) ring motifs. Weak C—H...O and C—H...π interactions may further stabilize the crystal structure.

A 6-chloronicotinate (6-Clnic) salt of a one-dimensional cationic nickel(II) coordination polymer with 4,4′-bipyridine (4,4′-bpy), namely, catena-poly[[[tetraaquanickel(II)]-μ-4,4′-bipyridine-κ2 N:N′] bis(6-chloronicotinate) tetrahydrate], {[Ni(C10H8N2)(H2O)4](C6H3ClNO2)2·4H2O} n or {[Ni(4,4′-bpy)(H2O)4](6-Clnic)2·4H2O} n , (1), was prepared by the reaction of nickel(II) sulfate heptahydrate, 6-chloronicotinic acid and 4,4′-bipyridine in a mixture of water and ethanol. The molecular structure of 1 comprises a one-dimensional polymeric {[Ni(4,4′-bpy)(H2O)4]2+} n cation, two 6-chloronicotinate anions and four water molecules of crystallization per repeating polymeric unit. The nickel(II) ion in the polymeric cation is octahedrally coordinated by four water molecule O atoms and by two 4,4′-bipyridine N atoms in the trans position. The 4,4′-bipyridine ligands act as bridges and, thus, connect the symmetry-related nickel(II) ions into an infinite one-dimensional polymeric chain extending along the b-axis direction. In the extended structure of 1, the polymeric chains of {[Ni(4,4′-bpy)(H2O)4]2+} n , the 6-chloronicotinate anions and the water molecules of crystallization are assembled into an infinite three-dimensional hydrogen-bonded network via strong O—H...O and O—H...N hydrogen bonds, leading to the formation of the representative hydrogen-bonded ring motifs: tetrameric R 2 4(8) and R 4 4(10) loops, a dimeric R 2 2(8) loop and a pentameric R 4 5(16) loop.

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.

Thiazolidine Ring

In the title compound, C19H18N2O3S, the thiazolidine ring makes dihedral angles of 46.97 (8) and 7.19 (9)° with the pyridine and benzene rings, respectively. The intramolecular structure is stabilized by a weak C—H...S hydrogen bond, which generates a S(6) graph-set motif, and a weak C—H...O contact. In the crystal, N—H...N and C—H...O hydrogen bonds leads to infinite one-dimensional chains along (201) and generate an R 2 2(7) ring-set motif. The crystal structure is further consolidated by weak π–π [centroid-to-centroid distance = 3.8204 (10) Å] interactions.
