The compound described by U4RhGa12 crystallizes in the cubic Im-3m space group. U(1) is bonded to six equivalent Ga(1) and six equivalent Ga(2) atoms to form UGa12 cuboctahedra that share corners with twelve equivalent U(1)Ga12 cuboctahedra, edges with twelve equivalent Ga(1)U4Ga8 cuboctahedra, faces with six equivalent U(1)Ga12 cuboctahedra, faces with six equivalent Ga(1)U4Ga8 cuboctahedra, and faces with two equivalent Rh(1)Ga6 octahedra. Rh(1) is bonded to six equivalent Ga(2) atoms to form RhGa6 octahedra that share corners with twenty-four equivalent Ga(1)U4Ga8 cuboctahedra and faces with eight equivalent U(1)Ga12 cuboctahedra. There are two inequivalent Ga sites. In the first Ga site, Ga(1) is bonded to four equivalent U(1), four equivalent Ga(1), and four equivalent Ga(2) atoms to form distorted GaU4Ga8 cuboctahedra that share corners with four equivalent Ga(1)U4Ga8 cuboctahedra, corners with four equivalent Rh(1)Ga6 octahedra, edges with eight equivalent U(1)Ga12 cuboctahedra, edges with eight equivalent Ga(1)U4Ga8 cuboctahedra, faces with four equivalent U(1)Ga12 cuboctahedra, and faces with six equivalent Ga(1)U4Ga8 cuboctahedra. The corner-sharing octahedral tilt angles are 50°. In the second Ga site, Ga(2) is bonded in a distorted single-bond geometry to four equivalent U(1), one Rh(1), and four equivalent Ga(1) atoms. is represented by the CIF file [CIF]
