Dicobalt copper bis-[orthophosphate(V)] monohydrate, Co(2.39)Cu(0.61)(PO(4))(2)·H(2)O.

ABSTRACT: In an attempt to hydro-thermally synthesize a phase with composition Co(2)Cu(PO(4))(2)·H(2)O, we obtained the title compound, Co(2.39)Cu(0.61)(PO(4))(2)·H(2)O instead. Chemical analysis confirmed the presence of copper in the crystal. The crystal structure of the title compound can be described as a three- dimensional network constructed from the stacking of two types of layers extending parallel to (010). These layers are made up from more or less deformed polyhedra: CoO(6) octa-hedra, (Cu/Co)O(5) square pyramids and PO(4) tetra-hedra. The first layer is formed by pairs of edge-sharing (Cu/Co)O(5) square pyramids linked via a common edge of each end of the (Cu/Co)(2)O(8) dimer to PO(4) tetra-hedra. The second layer is undulating and is built up from edge-sharing CoO(6) octa-hedra. The lin
