The compound described by Li2CrO2 is Ilmenite-like structured and crystallizes in the monoclinic C2/m space group. Li(1) is bonded to two equivalent O(1) and two equivalent O(2) atoms to form a mixture of distorted edge and corner-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 four equivalent Li(1) and two equivalent Cr(1) atoms to form a mixture of edge and corner-sharing OLi4Cr2 octahedra. The corner-sharing octahedral tilt angles range from 3-42°. In the second O site, O(2) is bonded to four equivalent Li(1) and two equivalent Cr(1) atoms to form a mixture of edge and corner-sharing OLi4Cr2 octahedra. The corner-sharing octahedral tilt angles range from 3-42°. is represented by the Crystallographic Information File (CIF) [CIF]
