In poly[[μ3-2,2′-(disulfanediyl)dibenzoato-κ5 O:O,O′:O′′,O′′′](1,10-phenanthroline-κ2 N,N′)cadmium(II)], [Cd(C14H8O4S2)(C12H8N2)] n , the asymmetric unit contains one CdII cation, one 2,2′-(disulfanediyl)dibenzoate anion (denoted dtdb2−) and one 1,10-phenanthroline ligand (denoted phen). Each CdII centre is seven-coordinated by five O atoms of bridging/chelating carboxylate groups from three dtdb2− ligands and by two N atoms from one phen ligand, forming a distorted pentagonal–bipyramidal geometry. The CdII cations are bridged by dtdb2− anions to give a two-dimensional (4,4) layer. The layers are stacked to generate a three-dimensional supramolecular architecture via a combination of aromatic C—H...π and π–π interactions. The thermogravimetric and luminescence properties of this compound were also investigated.

The title coordination polymer, [Cd3Co2(CN)12(C2H8N2)4]n, has an infinite two-dimensional network structure. The asymmetric unit is composed of two crystallographically independent CdIIatoms, one of which is located on a twofold rotation axis. There are two independent ethylenediamine (en) ligands, one of which bis-chelates to the Cd atom that sits in a general position, while the other bridges this Cd atom to that sitting on the twofold axis. The Cd atom located on the twofold rotation axis is linked to four equivalent CoIIIatomsviacyanide bridges, while the Cd atom that sits in a general position is connected to three equivalent CoIIIatomsviacyanide bridges. In this way, a series of trinuclear, tetranuclear and pentanuclear macrocycles are linked to form a two-dimensional network structure lying parallel to thebcplane. In the crystal structure, these two-dimensional networks are linkedviaN—H...N hydrogen bonds involving an en NH2H atom and a cyanide N atom, leading to the formation of a three-dimensional structure. This coordination polymer is only the second example involving a cyanometallate where the en ligand is present in both chelating and bridging coordination modes.

A novel manganese coordination polymer, poly[(μ5-thiophene-3,4-dicarboxylato)manganese(II)], [Mn(C6H2O4S)]n, was synthesized hydrothermally using 3,4-thiophenedicarboxylate (3,4-tdc2−) as the organic linker. The asymmetric unit of the complex contains an Mn2+cation and one half of a deprotonated 3,4-tdc2−anion, both residing on a twofold axis. Each Mn2+centre is six-coordinated by O atoms of bridging/chelating carboxylate groups from five 3,4-tdc2−anions, forming a slightly distorted octahedron. The Mn2+centres are bridged by 3,4-tdc2−anions to give an infinite two-dimensional layer which incorporates one-dimensional Mn–O gridlike chains, and in which the 3,4-tdc2−anion adopts a novel hexadentate chelating and μ5-bridging coordination mode. The fully deprotonated 3,4-tdc2−anion exhibits unexpected efficiency as a ligand towards the Mn2+centres, which it coordinates through all of its carboxylate O atoms to provide the novel coordination mode. The IR spectrum of the complex is also reported.

The reaction of copper(I) iodide with 1-[2-(cyclohexylsulfanyl)ethyl]pyridin-2(1H)-one (L, C13H19NOS) in acetonitrile/dichloromethane results in a crystalline coordination polymer, namely poly[bis{μ2-1-[2-(cyclohexylsulfanyl)ethyl]pyridin-2(1H)-one}tetra-μ3-iodidotetracopper(I)], [Cu4I4L2]n. The asymmetric unit comprises two ligand molecules, four copper(I) ions and four iodide ions. Interestingly, the O atoms are bound to the soft copper(I) ions. The stair-step clusters of Cu and I atoms in the asymmetric unit are linked repeatedly, giving rise to infinite chains along [100]. Neighbouring infinite chains are linked through theLmolecules, forming a two-dimensional brick-wall structure. These two-dimensional networks are stacked alternately along [001]. Additionally, there are intermolecular C—H...I hydrogen bonds and C—H...π interactions between the ligands.
