The structure described by Li2CoO2 is Ilmenite-like structured and crystallizes in the orthorhombic Immm space group. Li(1) is bonded to four equivalent O(1) atoms to form a mixture of edge and corner-sharing LiO4 trigonal pyramids. Co(1) is bonded in a square co-planar geometry to four equivalent O(1) atoms. O(1) is bonded to four equivalent Li(1) and two equivalent Co(1) atoms to form a mixture of edge and corner-sharing OLi4Co2 octahedra. The corner-sharing octahedral tilt angles range from 0-27°. is represented by the Crystallographic Information File (CIF) [CIF]
