Abstract: The monoclinic crystal structure of lithium chromium(III) diphosphate, LiCrP₂O₇, isotypic with other members of the series LiM^IIIP₂O₇ (M^III = Mn, Fe, V, Mo, Sc and In), was refined from laboratory X-ray powder diffraction data using the Rietveld method. The Cr³⁺ cation is bonded to six O atoms from five diphosphate anions to form a distorted octahedron. Links between the bent diphosphate anions and the Cr³⁺ cations result in a three-dimensional network, with tunnels filled by the Li⁺ cations in a considerably distorted tetrahedral environment of O atoms.
