Abstract

The cesium vanadium phosphate Cs[VIII2(PO4) (HPO4)2(H2O)2] (1) and the potassium vanadium phosphate K[(VIVO)-VIII(HPO4)3(H2O)2] (2) have been hydrothermally synthesized and structurally characterized by single-crystal X-ray methods. Green phosphate 1 is monoclinic, space group P21/a, with a = 10.004(1) Å, b = 17.812(3) Å, c = 6.370(2) Å, β = 97.02(2)°, and Z = 4, while green phosphate 2 is monoclinic, space group P21/n, with a = 6.399(3) Å, b = 10.275(2) Å, c = 17.810(2) Å, β = 96.12(2),° and Z = 4. These new reduced vanadium phosphates, built up from corner-sharing VO6 octahedra and PO4 tetrahedra, have anionic, three-dimensional framework structures that contain Cs+- and K+-filled voids.
