title: Poly[[diaquacobalt(II)]-mu-4,4'-bipyridine-kappa2N:N'-mu-p-phenylenebis(oxyacetato)-kappa2O:O'].
abstract: The title compound, [CoII(C10H8O6)(C10H8N2)(H2O)2]n, was obtained by the hydrothermal reaction of CoSO(4) with benzene-1,4-dioxydiacetate [systematic name: p-phenylenebis(oxyacetate)] and 4,4'-bipyridine (4,4'-bpy). The Co atom lies at an inversion center and the benzene-1,4-dioxydiacetate and 4,4'-bipyridine moieties lie about other inversion centers. The benzene-1,4-dioxydiacetate ligands bridge the octahedral Co(II) coordination centers, forming a one-dimensional zigzag chain. The chains are further bridged by 4,4'-bpy ligands, forming a novel two-dimensional supramolecular architecture. Hydrogen-bonding interactions between the coordinated water molecules and the carboxylate O atoms lead to the formation of a three-dimensional network structure.
