The structure described by Cd(NiO2)2 is Spinel structured and crystallizes in the tetragonal I4_1/amd space group. Ni(1) is bonded to six equivalent O(1) atoms to form distorted NiO6 octahedra that share corners with six equivalent Cd(1)O4 tetrahedra and edges with six equivalent Ni(1)O6 octahedra. Cd(1) is bonded to four equivalent O(1) atoms to form CdO4 tetrahedra that share corners with twelve equivalent Ni(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 56-65°. O(1) is bonded to three equivalent Ni(1) and one Cd(1) atom to form a mixture of distorted edge and corner-sharing OCdNi3 tetrahedra. is represented by the CIF file [CIF]
