The title compound, [CuNa(C4H3O7S)(C10H8N2)(H2O)3]n, consists of one CuIIcation, one NaIcation, one 2-sulfonatobutanedioate trianion (SSC3−), one 2,2′-bipyridyl (bpy) ligand and three coordinated water molecules as the building unit. The coordination of the CuIIcation is composed of two pyridyl N atoms, one water O atom and two carboxylate O atoms in a distorted square-pyramidal coordination geometry with an axial elongation. The NaIcation is six-coordinated by three water molecules and three carboxylate O atoms from three SSC3−ligands in a distorted octahedral geometry. Two SSC3−ligands link two CuIIcations to form a Cu2(SSC)2(bpy)2macrocyclic unit lying across an inversion centre, which is further linked by NaIcationsviaNa—O bonds to give a one-dimensional chain. Interchain hydrogen bonds link these chains to form a two-dimensional layer, which is further extended into a three-dimensional supramolecular framework through π–π stacking interactions. The thermal stability of the title compound has also been investigated.

The title compound, [Ni2(C9H6O4)2(C12H8N2)2(H2O)2], is isostructural with the ZnIIanalogue. Each NiIIatom is coordinated in a distorted octahedral geometry by three O atoms from two homophthalate anions, one aqua O atom and two 1,10-phenanthroline N atoms. The two NiIIatoms are linked by two bridging homophthalate dianions into a centrosymmetric dinuclear unit. The dinuclear units are linked into one-dimensional ladder-like chains along [100] by O—H...O hydrogen bonds between the coordinated water molecules and one of the O atoms of the carboxylatomethyl group.

The asymmetric unit in the structure of the title compound, [K2(C9H4O9S)(H2O)2]n, consists of two eight-coordinated KIcations, one 2,4-dicarboxy-5-sulfonatobenzoate dianion (H2SBTC2−), one bridging water molecule and one terminal coordinated water molecule. One KIcation is coordinated by three carboxylate O atoms and three sulfonate O atoms from four H2SBTC2−ligands and by two bridging water molecules. The second KIcation is coordinated by four sulfonate O atoms and three carboxylate O atoms from five H2SBTC2−ligands and by one terminal coordinated water molecule. The KIcations are linked by sulfonate groups to give a one-dimensional inorganic chain with cage-like K4(SO3)2repeat units. These one-dimensional chains are bridged by one of the carboxylic acid groups of the H2SBTC2−ligand to form a two-dimensional layer, and these layers are further linked by the remaining carboxylate groups and the benzene rings of the H2SBTC2−ligands to generate a three-dimensional framework. The compound displays a photoluminescent emission at 460 nm upon excitation at 358 nm. In addition, the thermal stability of the title compound has been studied.

In the title polymeric complex, {[Fe(C12H10N2)2(H2O)4](CH3C6H4SO3)2·2CH3OH}n, the FeIIcation, located on an inversion centre, is coordinated by four water molecules in the equatorial positions and two 1,2-bis(pyridin-4-yl)ethene molecules in the axial positions. This results in a distorted octahedral geometry for the [N2O4] coordination polyhedron. The 1,2-bis(pyridin-4-yl)ethene molecules bridge the FeIIcations, forming polymeric chains running along thea-axis direction. Stabilization of the crystal structure is provided by O—H...O hydrogen bonds; these are formed by coordinated water molecules as donors towards the O atoms of the methanol molecules and tosylate anions as acceptors of protons, leading to the formation of a three-dimensional supramolecular network. Weak C—H...O hydrogen bonds are also observed in the crystal.

The title compound, [Co(C6H6NO3S)2(H2O)2] n , was obtained from a mixture of Co(NO3)2·6H2O and a previously synthesized salt, namely CyNH3·NH2PhSO3, in a 1:1 ratio (Cy = cyclohexyl; Ph = phenyl). The crystal structure consists of a three-dimensional supramolecular framework, in which polymeric layers are interconnected via N—H...O and O—H...O hydrogen bonding. The polymeric layers are formed by an interconnection of neighbouring cobalt(II) cations via NH2PhSO3 − bridges. Each cobalt(II) cation is surrounded by four NH2PhSO3 − moieties and two water molecules, leading to a distorted octahedral environment.

Each FeIIIcation bridges two neighbouring FeIIIcations to form a one-dimensional [Fe2(pydc)4]nchain. The chains are connected by SrIIcations to form a three-dimensional framework. The topology type of this framework istfj. The structure displays O—H...O and C—H...O hydrogen bonding.

In the title compound, [Ni(C12H6O4)(C22H16N2O)2(H2O)2]n, the Ni2+cation resides on a centre of inversion in a slightly distorted octahedral [N2O4] environment. The two carboxylate groups of each naphthalene-2,6-dicarboxylate (NDC2−) ligand, which reside on centres of inversion, link the NiIIcations into a one-dimensional chain. Identical chains are linked by intermolecular hydrogen bonds between coordinated water molecules and the uncoordinated N atoms of 4-{4-[4-(pyridin-4-yl)phenoxy]phenyl}pyridine ligands to form (4,4)-topological sheets, and then the different sheets are interlocked in an inclined fashion to give a three-dimensional polycatenation network. The stability of the structure is further enhanced by π–π stacking interactions between pyridine and benzene rings.

The molecular structure of the title compound, [FePt(CN)4(C14H8N2)2(H2O)2]n, consists of one-dimensional polymeric [–Fe–NC–Pt(CN)2–CN–]∞chains. Two water molecules and two monodentate 1,4-bis(pyridin-4-yl)buta-1,3-diyne (bpb) ligand molecules complete the octahedral coordination sphere of the FeIIatoms. The Fe—N(py) bond length (py is pyridine) is 2.2700 (15) Å, Fe—N(cyanide) is 2.1185 (16) Å and the Fe—O distance is 2.1275 (14) Å. The water molecules are hydrogen bonded to either bpb ligands or cyanide groups of the planar [Pt(CN)4]2−anion of adjacent polymeric chains. These O—H...N hydrogen bonds, in conjunction with offset and tilted π–π stacking interactions between bpb ligands and cyanide groups, extend the one-dimensional chains into a three-dimensional assembly.
