metal-organic compounds
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(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.
