Abstract:The structure of the title compound, [Zn4(C2O4)(PO4)2(H2O)2]n, which was synthesized under hydrothermal conditions, consists of zinc phosphate layers joined by bridging oxalate ligands to generate a three-dimensional framework. An extended zinc phosphate layer lies parallel to the ab plane and within this layer there are helical chains, composed of ZnO6 octahedra and ZnO5 square pyramids, that run parallel to the b axis and coincide with the 21 screw element. The oxalate groups sit on crystallographic inversion centers.
