✦ Synopsis

The title compound has been prepared by hydrothermal synthesis and its crystal structure was determined by single crystal X-ray diffraction: space group P21/m, a = 4.8890(2), b = 14.3857(5), c = 7.9017(3) A, fi = 90.134(4) ° , wR2 = 0.123, R = 0.045. Cu 2+ has two different coordination polyhedra: an elongated square pyramidal [CuFO4] and square planar [CuO4] coordination in a 2:1 ratio. Edge-sharing doublepyramids and [CuO4] squares form zig-zag chains interconnected by [ZnO4] and [PO4] tetrahedra to form an open anionic framework structure whose channels are occupied by the K + ions.
