The compound described by LiNiO2 is Caswellsilverite-like structured and crystallizes in the tetragonal I4_1/amd space group. Li(1) is bonded to six O(1,1) atoms to form LiO6 octahedra that share corners with two equivalent Ni(1)O6 octahedra, corners with four equivalent Li(1)O6 octahedra, edges with four equivalent Li(1)O6 octahedra, and edges with eight equivalent Ni(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 0-10°. Ni(1) is bonded to six O(1,1) atoms to form NiO6 octahedra that share corners with two equivalent Li(1)O6 octahedra, corners with four equivalent Ni(1)O6 octahedra, edges with four equivalent Ni(1)O6 octahedra, and edges with eight equivalent Li(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 0-10°. There are three inequivalent O sites. In the first O site, O(1) is bonded to three equivalent Li(1) and three equivalent Ni(1) atoms to form a mixture of edge and corner-sharing OLi3Ni3 octahedra. The corner-sharing octahedral tilt angles range from 0-10°. In the second O site, O(1) is bonded to three equivalent Li(1) and three equivalent Ni(1) atoms to form a mixture of edge and corner-sharing OLi3Ni3 octahedra.
