摘要：

A lithium Mo(V) diphosphate LiMoOP2O7 has been synthesized for the first time. It crystallizes in the space group P2(1/n) with a = 16.046 (4) Angstrom, b = 11.951 (2) Angstrom, c = 9.937 (2) Angstrom, beta = 104.62 (2)degrees. Its original structure is built up from P2O7 groups and MoO6 octahedra forming intersecting tunnels, where the Li+ cations are located with a tetrahedral coordination. This phase belongs to the IB class of Mo(V) phosphates defined by Costentin et al. The [MoP2O8] framework indeed consists of MoP2O11 units built up from one P2O7 group sharing two apices with the same MoO6 octahedron; the MoP2O11 units share their apices forming [MoP2O10]infinity chains running along a and b and the [<(1)over bar04>] direction. This phase exhibits a classical paramagnetic behavior, with theta -9.8 K and mu = 1.58 mu(B). (C) 1995 Academic Press, Inc.
