The title compound, (C21H20OP)(C19H15N4)[CuCl4], was obtained by reacting CuCl2·2H2O with a mixture of one equivalent of acetonyltriphenylphosphonium chloride and one equivalent of 2,3,5-triphenyltetrazolium chloride in acetonitrile. In the structure, the Cu centre in the dianion is bonded to four chloride ligands and adopts a distorted tetrahedral geometry. The phosphonium cation likewise adopts the expected tetrahedral geometry. The tetrazolium ring forms dihedral angles of 77.68 (10), 26.85 (11) and 66.48 (10)° with the planes of the benzene rings of the substituent groups. In the crystal, weak C—H...Cl hydrogen-bonding interactions involving both cations and the anion give rise to a three-dimensional supramolecular structure.

The title CoII coordination polymer, {[Co(C9H4O6)(C14H14N4)]·H2O} n , was obtained by reaction of Co(NO3)2·6H2O, benzene-1,3,5-tricarboxylic acid (H3BTC) and 1,3-bis(imidazol-1-ylmethyl)benzene (L). Each CoII cation is four-coordinated by an O2N2 donor set in a distorted tetrahedral geometry. The CoII centers are connected into a one-dimensional double-stranded chain by HBTC anions and L ligands. The chains are further connected through hydrogen-bonding interactions between the hydroxyl groups of adjacent HBTC anions and face-to-face π–π interactions between the benzene rings of adjacent L ligands [average face-to-face distance of 3.427 (3) Å], resulting in the formation of a three-dimensional supramolecular structure.

The title compound, C14H12ClNO4S, crystallizes with two molecules in the asymmetric unit. The dihedral angles between the benzene rings are 89.68 (1) (molecule 1) and 82.9 (1)° (molecule 2). In each molecule, intramolecular N—H...O hydrogen bonds between the amide H atom and the methoxy O atom generateS(6) loops. In the crystal, molecule 2 is linked into inversion dimers through pairs of C—H...O interactions, forming anR22(8) ring motif. Molecules 1 and 2 are further linked along theb-axis direction through C—H...π interactions. The crystal structure is further stabilized by several π–π stacking interactions [centroid–centroid separations = 3.7793 (1), 3.6697 (1) and 3.6958 (1) Å], thus generating a three-dimensional architecture.
