LiMoP₂O₇

The structure of lithium molybdenum(III) diphosphate has been determined for the first time from single-crystal X-ray diffraction data. LiMoP₂O₇, which crystallizes in the space group P2₁, is isotypic with LiVP₂O₇ and LiFeP₂O₇; it has a tunnel structure consisting of corner-sharing MoO₆ octahedra and diphosphate groups forming chains running along b. The Li⁺ ions have tetrahedral coordination geometry. The geometry of the different polyhedra can be compared with those in LiVP₂O₇.
