The structure described by Li2Cr5(PO4)4 crystallizes in the triclinic P-1 space group. Li(1) is bonded in a 4-coordinate geometry to one O(2), one O(3), one O(7), and one O(8) atom. There are three inequivalent Cr sites. In the first Cr site, Cr(1) is bonded to one O(1), one O(3), one O(4), one O(5), and one O(6) atom to form CrO5 trigonal bipyramids that share corners with two equivalent P(1)O4 tetrahedra and corners with three equivalent P(2)O4 tetrahedra. In the second Cr site, Cr(2) is bonded in a square co-planar geometry to one O(2), one O(4), one O(6), and one O(8) atom. In the third Cr site, Cr(3) is bonded in a square co-planar geometry to two equivalent O(5) and two equivalent O(7) atoms. There are two inequivalent P sites. In the first P site, P(1) is bonded to one O(1), one O(2), one O(5), and one O(8) atom to form PO4 tetrahedra that share corners with two equivalent Cr(1)O5 trigonal bipyramids. In the second P site, P(2) is bonded to one O(3), one O(4), one O(6), and one O(7) atom to form PO4 tetrahedra that share corners with three equivalent Cr(1)O5 trigonal bipyramids. There are eight inequivalent O sites. In the first O site, O(1) is bonded in a bent 120 degrees geometry to one Cr(1) and one P(1) atom. In the second O site, O(2) is bonded in a distorted trigonal non-coplanar geometry to one Li(1), one Cr(2), and one P(1) atom. In the third O site, O(3) 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(4) is bonded in a trigonal planar geometry to one Cr(1), one Cr(2), and one P(2) atom. In the fifth O site, O(5) is bonded in a 3-coordinate geometry to one Cr(1), one Cr(3), and one P(1) atom. In the sixth O site, O(6) is bonded in a trigonal planar geometry to one Cr(1), one Cr(2), and one P(2) atom.
