The structure described by LiCr2P3O10 crystallizes in the monoclinic P2_1/m space group. Li(1) is bonded in a square co-planar geometry to two equivalent O(1) and two equivalent O(6) atoms. Cr(1) is bonded to one O(1), one O(2), one O(4), one O(6), and two equivalent O(3) atoms to form distorted CrO6 octahedra that share  a cornercorner with one P(1)O4 tetrahedra, corners with two equivalent P(2)O4 tetrahedra, corners with three equivalent P(3)O4 tetrahedra, and edges with two equivalent Cr(1)O6 octahedra. There are three inequivalent P sites. In the first P site, P(1) is bonded to one O(5), one O(7), and two equivalent O(1) atoms to form PO4 tetrahedra that share corners with two equivalent Cr(1)O6 octahedra,  a cornercorner with one P(2)O4 tetrahedra, and  a cornercorner with one P(3)O4 tetrahedra. The corner-sharing octahedral tilt angles are 39°. In the second P site, P(2) is bonded to one O(2), one O(5), and two equivalent O(6) atoms to form PO4 tetrahedra that share corners with four equivalent Cr(1)O6 octahedra and  a cornercorner with one P(1)O4 tetrahedra. The corner-sharing octahedral tilt angles range from 49-59°. In the third P site, P(3) is bonded to one O(4), one O(7), and two equivalent O(3) atoms to form PO4 tetrahedra that share corners with six equivalent Cr(1)O6 octahedra and  a cornercorner with one P(1)O4 tetrahedra. The corner-sharing octahedral tilt angles range from 43-57°. There are seven inequivalent O sites. In the first O site, O(1) is bonded in a distorted trigonal planar geometry to one Li(1), one Cr(1), and one P(1) atom. In the second O site, O(2) is bonded in a distorted trigonal planar geometry to two equivalent Cr(1) and one P(2) atom. In the third O site, O(3) is bonded in a 2-coordinate geometry to two equivalent Cr(1) and one P(3) atom. In the fourth O site, O(4) is bonded in a distorted trigonal planar geometry to two equivalent Cr(1) and one P(3) atom. In the fifth O site, O(5) is bonded in a bent 120 degrees geometry to one P(1) and one P(2) atom. In the sixth 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 seventh O site, O(7) is bonded in a bent 150 degrees geometry to one P(1) and one P(3) atom. is represented by the CIF card [CIF]
