The crystal structure described by LiCr2P3O13 crystallizes in the triclinic P-1 space group. Li(1) is bonded in a 2-coordinate geometry to one O(2) and one O(8) atom. There are two inequivalent Cr sites. In the first Cr site, Cr(1) is bonded to one O(1), one O(10), one O(11), one O(6), one O(8), and one O(9) atom to form distorted CrO6 octahedra that share  a cornercorner with one P(1)O4 tetrahedra,  a cornercorner with one P(2)O4 tetrahedra, and corners with three equivalent P(3)O4 tetrahedra. In the second Cr site, Cr(2) is bonded in a 6-coordinate geometry to one O(12), one O(13), one O(2), one O(3), one O(4), and one O(5) atom. There are three 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(7) atom to form PO4 tetrahedra that share  a cornercorner with one Cr(1)O6 octahedra and  a cornercorner with one P(2)O4 tetrahedra. The corner-sharing octahedral tilt angles are 22°. In the second P site, P(2) is bonded to one O(10), one O(13), one O(3), and one O(7) atom to form PO4 tetrahedra that share  a cornercorner with one Cr(1)O6 octahedra and  a cornercorner with one P(1)O4 tetrahedra.
