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.

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 salt (I), C6H8N+·C20H17O8−, comprises a 2-methylpyridinium cation and a 2,3-bis(4-methylbenzoyloxy)succinate mono-anion while the salt (II), 2C6H8N+·2C20H17O8−·5H2O, consists of a pair of 4-methylpyridinium cations and 2,3-bis(4-methylbenzoyloxy)succinate mono-anions and five water molecules of solvation in the asymmetric unit. In (I), the dihedral angle between the aromatic rings of the anion is 40.41 (15)°, comparing with 43.0 (3) and 85.7 (2)° in the conformationally dissimilar anion molecules in (II). The pyridine ring of the cation in (I) is inclined at 23.64 (16) and 42.69 (17)° to the two benzene moieties of the anion. In (II), these comparative values are 4.7 (3), 43.5 (3)° and 43.5 (3), 73.1 (3)° for the two associated cation and anion pairs. The crystal packing of (I) is stabilized by inter-ionic N—H...O, O—H...O and C—H...O hydrogen bonds as well as weak C—H...π interactions, linking the ions into infinite chains along [100]. In the crystal packing of (II), the anions and cations are also linked by N—H...O and O—H...O hydrogen bonds involving also the water molecules, giving a two-dimensional network across (001). The crystal structure is also stabilized by weak C—H...O and C—H...π interactions.

The asymmetric unit of the title coordination polymer [Zn(C9H6NO2)2(C10H8N4)] n , consists of one ZnII cation, one bidentate 1H-indole-5-carboxylate (I5C) anion and half of a 4,4′-azobipyridine (Abpy) neutral ligand. In the coordination polyhedron, the ZnII ion adopts a distorted octahedral geometry. The coordination polymer is stabilized by a combination of N—H...O and C—H...π interactions, which leads to the formation of wave-like two-dimensional coordination polymeric layers.

The molecules in the title compound, C7H8N4, are linked into sheets by a combination of C—H...N hydrogen bonds and π–π interactions. The hydrogen bonds generate two-dimensional networks with a C(6) chain motif. There are two planar symmetry-independent molecules in the asymmetric unit, with a dihedral angle of 4.29 (8)° between their least-squares mean planes.

The asymmetric unit of the optically resolved title salt, C8H12N+·C4H5O4S−, contains a 1-phenylethanaminium monocation and a thiomalate (3-carboxy-2-sulfanylpropanoate) monoanion. The absolute configurations of the cation and the anion are determined to beSandR, respectively. In the crystal, cation–anion N—H...O hydrogen bonds, together with anion–anion O—H...O and S—H...O hydrogen bonds, construct a two-dimensional supramolecular sheet parallel to theabplane. The two-dimensional sheet is linked with the upper and lower sheets through C—H...π interactions to stack along thecaxis.

The title compound, C8H4BrNO2·0.5H2O, has a single planar molecule in the asymmetric unit with the non-H atoms having a mean deviation from planarity of 0.028 Å. There is also a half of a water molecule (twofold symmetry) present in the asymmetric unit, which hydrogen bonds with the isatin molecules through O—H...O and N—H...O hydrogen bonds to form a two-dimensional framework in theabplane. There are close Br...O contacts of 2.999 (2) Å to link the layers. The nine-membered rings of the isatin molecules stack along theaaxis with parallel slipped π–π interactions [inter-centroid distances = 3.6989 (19) and 4.1227 (19) Å].

The asymmetric unit of the title polymer, [Co2(C3H3O4)2Cl2(H2O)2]n, comprises one CoIIatom, one water molecule, one singly deprotonated malonic acid molecule (HMal−; systematic name 2-carboxyacetate) and one Cl−anion. The CoIIatom is octahedrally coordinated by the O atom of a water molecule, by one terminally bound carboxylate O atom of an HMal−anion and by two O atoms of a chelating HMal−anion, as well as by two Cl−anions. The Cl−anions bridge two CoIIatoms, forming a centrosymmetric Co2Cl2core. Each malonate ligand is involved in the formation of six-membered chelate rings involving one CoIIatom of the dinuclear unit and at the same time is coordinating to another CoIIatom of a neighbouring dinuclear unit in a bridging mode. The combination of chelating and bridging coordination modes leads to the formation of a two-dimensional coordination polymer extending parallel to (001). Within a layer, O—Hwater...Cl and O—Hwater...O hydrogen bonds are present. Adjacent layers are linked through O—H...O=C hydrogen bonds involving the carboxylic acid OH and carbonyl groups.
