LiCr2O4 crystallizes in the orthorhombic Amm2 space group. Li(1) is bonded in a 4-coordinate geometry to two equivalent O(1) and two equivalent O(3) atoms. There are two inequivalent Cr sites. In the first Cr site, Cr(1) is bonded in a 5-coordinate geometry to one O(2) and four equivalent O(3) atoms. In the second Cr site, Cr(2) is bonded to two equivalent O(1), two equivalent O(2), and two equivalent O(3) atoms to form edge-sharing CrO6 octahedra. There are three inequivalent O sites. In the first O site, O(1) is bonded in a square co-planar geometry to two equivalent Li(1) and two equivalent Cr(2) atoms. In the second O site, O(2) is bonded in a distorted T-shaped geometry to one Cr(1) and two equivalent Cr(2) atoms. In the third O site, O(3) is bonded in a rectangular see-saw-like geometry to one Li(1), one Cr(2), and two equivalent Cr(1) atoms.
