The structure described by Li2Cr4O13 crystallizes in the orthorhombic C222_1 space group. Li(1) is bonded to one O(1), one O(4), one O(5), one O(6), and one O(7) atom to form distorted LiO5 trigonal bipyramids that share corners with two equivalent Cr(1)O4 tetrahedra and corners with three equivalent Cr(2)O4 tetrahedra. There are two inequivalent Cr sites. In the first Cr site, Cr(1) is bonded to one O(1), one O(2), one O(3), and one O(4) atom to form CrO4 tetrahedra that share  a cornercorner with one Cr(1)O4 tetrahedra,  a cornercorner with one Cr(2)O4 tetrahedra, and corners with two equivalent Li(1)O5 trigonal bipyramids. In the second Cr site, Cr(2) is bonded to one O(3), one O(5), one O(6), and one O(7) atom to form CrO4 tetrahedra that share  a cornercorner with one Cr(1)O4 tetrahedra and corners with three equivalent Li(1)O5 trigonal bipyramids. There are seven inequivalent O sites. In the first O site, O(6) is bonded in a bent 120 degrees geometry to one Li(1) and one Cr(2) atom. In the second O site, O(7) is bonded in a bent 150 degrees geometry to one Li(1) and one Cr(2) atom. In the third O site, O(1) is bonded in a bent 150 degrees geometry to one Li(1) and one Cr(1) atom. In the fourth O site, O(2) is bonded in a linear geometry to two equivalent Cr(1) atoms. In the fifth O site, O(3) is bonded in a bent 120 degrees geometry to one Cr(1) and one Cr(2) atom. In the sixth O site, O(4) is bonded in a bent 150 degrees geometry to one Li(1) and one Cr(1) atom. In the seventh O site, O(5) is bonded in a distorted linear geometry to one Li(1) and one Cr(2) atom. is represented by the Crystallographic Information File (CIF) [CIF]
