The compound described by CuRh2O4 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 Cu(1)O4 tetrahedra and edges with six equivalent Rh(1)O6 octahedra. Cu(1) is bonded to four equivalent O(1) atoms to form CuO4 tetrahedra that share corners with twelve equivalent Rh(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 56-63°. O(1) is bonded in a rectangular see-saw-like geometry to three equivalent Rh(1) and one Cu(1) atom. is represented by the CIF file [CIF]
