The material described by Li2NiO2 is Ilmenite-like structured and crystallizes in the monoclinic C2/m space group. Li(1) is bonded to four equivalent O(1) atoms to form a mixture of distorted edge and corner-sharing LiO4 trigonal pyramids. Ni(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 Ni(1) atoms to form a mixture of edge and corner-sharing OLi4Ni2 octahedra. The corner-sharing octahedral tilt angles range from 0-34°. is represented by the CIF file [CIF]
