The structure described by LiCr2(PO4)3 crystallizes in the monoclinic C2/c space group. Li(1) is bonded in a 6-coordinate geometry to two equivalent O(1), two equivalent O(4), and two equivalent O(6) atoms. Cr(1) is bonded to one O(1), one O(2), one O(3), one O(4), one O(5), and one O(6) atom to form CrO6 octahedra that share corners with two equivalent P(1)O4 tetrahedra and corners with four equivalent P(2)O4 tetrahedra. There are two inequivalent P sites. In the first P site, P(1) is bonded to two equivalent O(2) and two equivalent O(4) atoms to form PO4 tetrahedra that share corners with four equivalent Cr(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 26-40°. In the second P site, P(2) is bonded to one O(1), one O(3), one O(5), and one O(6) atom to form PO4 tetrahedra that share corners with four equivalent Cr(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 17-48°. There are six inequivalent O sites. In the first O site, O(5) is bonded in a bent 150 degrees geometry to one Cr(1) and one P(2) atom. In the second O site, O(6) is bonded in a 3-coordinate geometry to one Li(1), one Cr(1), and one P(2) atom. In the third O site, O(1) is bonded in a 3-coordinate geometry to one Li(1), one Cr(1), and one P(2) atom. In the fourth O site, O(2) is bonded in a bent 150 degrees geometry to one Cr(1) and one P(1) atom. In the fifth O site, O(3) is bonded in a linear geometry to one Cr(1) and one P(2) atom. In the sixth O site, O(4) is bonded in a 3-coordinate geometry to one Li(1), one Cr(1), and one P(1) atom. is represented by the Crystallographic Information File (CIF) [CIF]
