Green crystals of the title compound, nickel dizinc phosphate tetrahydrate, have been prepared hydrothermally. The compound is isostructural with hopeite, Zn3(PO4)2·4H2O, with nickel completely substituted for zinc at the octahedral site, resulting in [ZnPO4]− layers bridged by cis Ni(H2O)4O2 octahedra. O—HO hydrogen bonds help to stabilize the structure. The Ni atom and two water O atoms occupy special positions with mirror symmetry.

The title compound, [Ga(CH3)2(C21H17N2O)], synthesized by the reaction of trimethylgallium and 4-methyl-2,6-bis(phenyliminomethyl)phenol, has the Ga atom in a tetrahedral geometry; two molecules form a dimer through a π–π interaction.

In the title complex, [Cu(C36H36N4O4)(ClO4)](ClO4)·C3H7N, the coordination number of the CuII atom is 5 and the coordination configuration is best described as distorted tetragonal–pyramidal. There is a 13-membered macrocyclic ring in the molecule. One perchlorate anion and the dimethylformamide molecule do not participate in coordination. There are four intramolecular hydrogen bonds in the structure and these constrain the conformation of the macrocycle and enhance its stability.

The title centrosymmetric compound, [Cu2(C8H7O3)4(C2H3N)2], is a carboxylate-bridged dinuclear CuII complex with four phenoxyacetate and two acetonitrile molecules as ligands. Each of the four phenoxyacetate anions straddles the pair of Cu atoms, the Cu—Cu distance being 2.6618 (10) Å. A weak C—Hπ interaction connects the dinuclear CuII units into a one-dimensional chain.

In the title compound, [Cu(C10H8O6)(C5H5N)3]·H2O, the coordination geometry around the CuII atom is distorted square-pyramidal, and the Cu—N bond at the apical position lies on a twofold axis. The m-phenylenedioxydiacetate ligand also has twofold symetry and acts as bridge to link Cu atoms to form infinite chains along the c axis. The solvent water molecule connects two adjacent carboxylate groups of the m-phenylenedioxydiacetates on the same chain via hydrogen bonds.

In the title compound, [Zn(C8H3NO6)(C3H4N2)2]n, each ZnII atom is four-coordinated and bridged by a 5-nitrobenzene-1,3-dicarboxylate ligand to form a one-dimensional herring-bone chain. Interchain hydrogen bonds connect the chains to produce a two-dimensional double-sheet layer. In the crystal structure, all double-sheet layers are stabilized via interlayer π–π interactions between adjacent benzene rings.

The title compound, C22H18O2, contains three benzene rings that are not coplanar as a result of steric strain. The molecules are packed in columns along the a axis in the crystal structure, and classical hydrogen bonds are not found.

In the title compound, {[Zn(C10H8O6)(C5H5N)2(H2O)]}n, the coordination geometry around the ZnII atom is distorted square-pyramidal, and the Zn—OH2 bond at the apical position lies on a twofold axis. The bis-monodentate benzene-1,4-dioxyacetate ligand has inversion symmetry and acts as a bridge to link Zn atoms to form an infinite zigzag chain. Hydrogen bonds between the coordinated water molecule and the free carboxylate O atoms link the chains along the b axis into a two-dimensional layer.
