The new iron phosphate KZnFe(PO4)(2) has been synthesized by flux method and solid state reaction, and characterized by X-ray diffraction, IR, Mossbauer spectroscopy and magnetic susceptibility. This compound crystallizes in the monoclinic space group C2/c with the cell parameters: a = 13.514(4) angstrom, b = 13.273(6) angstrom, c=8.742(3) angstrom and beta = 100.07(2)degrees. It displays strong similarities with the phosphates KCoAl (PO4)(2) and NaCoPO4 and features some analogies with the zeolite-ABW structural type. 3D framework is built up by a corner-sharing between MO4 (M = 0.5 Zn + 0.5 Fe) and PO4 tetrahedra. The K+ ions are found within crossing tunnels perpendicular to the (1 0 0), (0 1 0) and (0 0 1) planes, delimited by this framework. A Mossbauer study confirmed the presence of Fe3+ ions in a tetrahedral environment. Magnetic measurements revealed an antiferromagnetic behavior with T-N = 8.5 K. (C) 2014 Elsevier Ltd.
