The crystal structure described by LiCrPO5 crystallizes in the orthorhombic Pnma space group. Li(1) is bonded to one O(1), one O(2), and two equivalent O(3) atoms to form LiO4 tetrahedra that share corners with four equivalent Cr(1)O6 octahedra and corners with three equivalent P(1)O4 tetrahedra. The corner-sharing octahedral tilt angles range from 57-72°. Cr(1) is bonded to two equivalent O(2), two equivalent O(3), and two equivalent O(4) atoms to form CrO6 octahedra that share corners with four equivalent Li(1)O4 tetrahedra, corners with four equivalent P(1)O4 tetrahedra, and edges with two equivalent Cr(1)O6 octahedra. P(1) is bonded to one O(1), one O(4), and two equivalent O(3) atoms to form PO4 tetrahedra that share corners with four equivalent Cr(1)O6 octahedra and corners with three equivalent Li(1)O4 tetrahedra. The corner-sharing octahedral tilt angles range from 47-53°. There are four inequivalent O sites. In the first O site, O(1) is bonded in a linear geometry to one Li(1) and one P(1) atom. In the second O site, O(2) is bonded in a trigonal planar geometry to one Li(1) and two equivalent Cr(1) atoms. In the third O site, O(3) is bonded in a trigonal planar geometry to one Li(1), one Cr(1), and one P(1) atom. In the fourth O site, O(4) is bonded in a 3-coordinate geometry to two equivalent Cr(1) and one P(1) atom. is represented by the CIF card [CIF]
