摘要：

Lead(II) divanadium(IV) diphosphate, PbV2P2O10, M(r) = 531.01, monoclinic, P2(1)/c, a= 5.2306(4), b = 8.5805(9), c = 16.790(1) angstrom, beta = 91.01 (1)-degrees, V = 753.4 (1) angstrom3, Z = 4, D(x) = 4.68 Mg M-3, lambda(Mo Kalpha) = 0.71073 angstrom, mu = 25.3 mm-1, F(000) = 952, T = 294 K, R = 0.032, wR = 0.035 for 1809 reflections with I > 3sigma(I), out of 6606 unique reflections measured. This phosphate is isotypic with BaV2P2O10. Its structure consists of similar V2P2O14 units built up from one VO6 octahedron, one VO5 pyramid and two PO4 tetrahedra. These units delimit tunnels where the Pb ions are located. The coordination of Pb is different from that of Ba.
