metal-organic compounds
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.
