The structure described by FeCu(RhSe2)4 is Spinel-derived structured and crystallizes in the cubic F-43m space group. Fe(1) is bonded to four equivalent Se(2) atoms to form FeSe4 tetrahedra that share corners with twelve equivalent Rh(1)Se6 octahedra. The corner-sharing octahedral tilt angles are 58°. Rh(1) is bonded to three equivalent Se(1) and three equivalent Se(2) atoms to form RhSe6 octahedra that share corners with three equivalent Fe(1)Se4 tetrahedra, corners with three equivalent Cu(1)Se4 tetrahedra, and edges with six equivalent Rh(1)Se6 octahedra. Cu(1) is bonded to four equivalent Se(1) atoms to form CuSe4 tetrahedra that share corners with twelve equivalent Rh(1)Se6 octahedra. The corner-sharing octahedral tilt angles are 58°. There are two inequivalent Se sites. In the first Se site, Se(1) is bonded to three equivalent Rh(1) and one Cu(1) atom to form distorted SeCuRh3 trigonal pyramids that share corners with three equivalent Se(1)CuRh3 trigonal pyramids, corners with nine equivalent Se(2)FeRh3 trigonal pyramids, and edges with three equivalent Se(1)CuRh3 trigonal pyramids. In the second Se site, Se(2) is bonded to one Fe(1) and three equivalent Rh(1) atoms to form distorted SeFeRh3 trigonal pyramids that share corners with three equivalent Se(2)FeRh3 trigonal pyramids, corners with nine equivalent Se(1)CuRh3 trigonal pyramids, and edges with three equivalent Se(2)FeRh3 trigonal pyramids. is represented by the CIF card [CIF]
