The compound described by Co(NiO2)2 is Spinel structured and crystallizes in the cubic Fd-3m space group. Co(1) is bonded to four equivalent O(1) atoms to form CoO4 tetrahedra that share corners with twelve equivalent Ni(1)O6 octahedra. The corner-sharing octahedral tilt angles are 57°. Ni(1) is bonded to six equivalent O(1) atoms to form NiO6 octahedra that share corners with six equivalent Co(1)O4 tetrahedra and edges with six equivalent Ni(1)O6 octahedra. O(1) is bonded in a distorted rectangular see-saw-like geometry to one Co(1) and three equivalent Ni(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
