Li2CrO2 crystallizes in the triclinic P-1 space group. There are two inequivalent Li sites. In the first Li site, Li(1) is bonded to two equivalent O(1) and two equivalent O(2) atoms to form a mixture of corner and edge-sharing LiO4 tetrahedra. In the second Li site, Li(2) is bonded to two equivalent O(1) and two equivalent O(2) atoms to form a mixture of corner and edge-sharing LiO4 tetrahedra. Cr(1) is bonded in a square co-planar geometry to two equivalent O(1) and two equivalent O(2) atoms. There are two inequivalent O sites. In the first O site, O(1) is bonded to two equivalent Li(1), two equivalent Li(2), and two equivalent Cr(1) atoms to form a mixture of distorted corner and edge-sharing OLi4Cr2 pentagonal pyramids. In the second O site, O(2) is bonded to two equivalent Li(1), two equivalent Li(2), and two equivalent Cr(1) atoms to form a mixture of distorted corner and edge-sharing OLi4Cr2 pentagonal pyramids.

In the first Li site, Li(1) is bonded to two equivalent O(1) and two equivalent O(2) atoms to form a mixture of corner and edge-sharing LiO4 tetrahedra. Both Li(1)-O(1) bond lengths are 2.01 Å. There is one shorter (2.01 Å) and one longer (2.03 Å) Li(1)-O(2) bond length. In the second Li site, Li(2) is bonded to two equivalent O(1) and two equivalent O(2) atoms to form a mixture of corner and edge-sharing LiO4 tetrahedra. There is one shorter (2.01 Å) and one longer (2.02 Å) Li(2)-O(1) bond length. There is one shorter (2.00 Å) and one longer (2.01 Å) Li(2)-O(2) bond length. Cr(1) is bonded in a square co-planar geometry to two equivalent O(1) and two equivalent O(2) atoms. Both Cr(1)-O(1) bond lengths are 2.08 Å.
