In the title salt (C7H11N2)2[Cu(C4N2S2)2], the Cu2+ ion is coordinated by four S atoms of two 1,2-dicyanoethene-1,2-dithiolate (or maleonitriledithiolate, mnt2−) ligands in an approximate square-planar geometry. The Cu atom is located on an inversion centre. Strong hydrogen-bonding interactions between the pyridinium proton and the CN groups of the mnt2− ligand link anions and cations into a one-dimensional chain structure.

The centrosymmetric title compound, [PdCl2(C19H17P)2], crystallizes with a square-planar geometry about the PdII metal centre. The most important bond distances include Pd—P (trans P) of 2.3404 (9) Å and Pd—Cl (trans Cl) of 2.2977 (12) Å. Weak intra- and intermolecular hydrogen bonding is observed in the solid-state structure between the chloro and phenyl H atoms. This weak intermolecular hydrogen-bonding pattern forms a one-dimensional chain along the b axis.

The title mononuclear CuIIcomplex, [Cu(C8H5O3)2(C10H8N2)], is comprised of a CuIIcation, two 4-formylbenzoate (L−) ligands and a 2,2′-bipyridine (bipy) ligand. The CuIIion and bipy ligand lie on a crystallographic twofold rotation axis; the CuIIion is coordinated by two N atoms from one bipy ligand and two O atoms from two different carboxylate groups of twoL−ligands, exhibiting effectively a distorted square-planar geometry. The complex molecules are interlinked to generate two-dimensional supramolecular layers in theabplane, formed by C—H...O hydrogen bonds, where the O acceptor is the O atom from the carboxylate group not involved in coordination to the CuIIion. The two-dimensional layers are stacked in a sequenceviaC—H...O hydrogen-bonding interactions where the formyl O atom acts as acceptor.

The title compound, {[Cu(NH3)4][Cu(CN)3]2}n, features a CuI–CuIImixed-valence CuCN framework based on {[Cu2(CN)3]−}nanionic layers and [Cu(NH3)4]2+cations. The asymmetric unit contains two different CuIions and one CuIIion which lies on a centre of inversion. Each CuIion is coordinated to three cyanide ligands with a distorted trigonal–planar geometry, while the CuIIion is ligated by four ammine ligands, with a distorted square-planar coordination geometry. The interlinkage between CuIions and cyanide bridges produces a honeycomb-like {[Cu2(CN)3]−}nanionic layer containing 18-membered planar [Cu(CN)]6metallocycles. A [Cu(NH3)4]2+cation fills each metallocyclic cavity within pairs of exactly superimposed {[Cu2(CN)3]−}nanionic layers, but there are no cations between the layers of adjacent pairs, which are offset. Pairs of N—H...N hydrogen-bonding interactions link the N—H groups of the ammine ligands to the N atoms of cyanide ligands.

The asymmetric unit of the title coordination polymer, [Co(C9H4N2O4)(C2H4N4)] n or [Co(L 1)(L 2)] n , consists of one crystallographically independent Co2+ centre, one L 1 2− ligand and one L 2 ligand (L 1 = 1H-benzimidazole-5,6-dicarboxylic acid, L 2 = 3-amino-1,2,4-triazole). The Co2+ centre is coordinated by two carboxylato-O atoms from two independent L 1 2− ligands and two nitrogen atoms from L 2 and another L 1 ligand. Thus, the metal center adopts a four-coordinate mode, forming a tetrahedral geometry. Interestingly, through the combination of two L 1 2−, two L 2 ligands and two Co2+ ions, a basic repeating unit is constructed, resulting in the formation of a one-dimensional straight chain structure. These chains are further expanded to the final three-dimensional framework via N—H...O hydrogen-bonding interactions.

In the title compound, {[Ag(C6H8N2)(H2O)](C6H4Cl2NO3S)} n , the AgI ion is three-coordinated by two N atoms from two symmetry-related 2,3-dimethylpyrazine (dmp) ligands, and one water O atom in a distorted trigonal–planar geometry. The dmp ligands bridge AgI ions to form a one-dimensional chain structure with charge-balancing 4-amino-2,5-dichlorobenzenesulfonate anions. In the crystal structure, intermolecular O—H...O and N—H...O hydrogen bonds form a two-dimensional network.

The nitrite O atoms of the (E)-2-nitriminoimidazolidin-1-yl group act as the acceptors of three N—H...O hydrogen bonds from the N atom of the imidazole ring, resulting in a one-dimensional chain. C—H...O hydrogen-bonding interactions are also observed in this complex, extending the structure into a two-dimensional supramolecular sheet.
