The material structure described by Ni(RhO2)2 is Spinel structured and crystallizes in the tetragonal I4_1/amd space group. Rh(1) is bonded to six equivalent O(1) atoms to form RhO6 octahedra that share corners with six equivalent Ni(1)O4 tetrahedra and edges with six equivalent Rh(1)O6 octahedra. Ni(1) is bonded to four equivalent O(1) atoms to form NiO4 tetrahedra that share corners with twelve equivalent Rh(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 52-61°. O(1) is bonded in a rectangular see-saw-like geometry to three equivalent Rh(1) and one Ni(1) atom. is represented by the CIF card [CIF]
