The structure described by Zn(NiO2)2 is Spinel structured and crystallizes in the cubic Fd-3m space group. Ni(1) is bonded to six equivalent O(1) atoms to form NiO6 octahedra that share corners with six equivalent Zn(1)O4 tetrahedra and edges with six equivalent Ni(1)O6 octahedra. Zn(1) is bonded to four equivalent O(1) atoms to form ZnO4 tetrahedra that share corners with twelve equivalent Ni(1)O6 octahedra. The corner-sharing octahedral tilt angles are 59°. O(1) is bonded to three equivalent Ni(1) and one Zn(1) atom to form a mixture of distorted edge and corner-sharing OZnNi3 trigonal pyramids. is represented by the Crystallographic Information File (CIF) [CIF]
