The material described by Rh3Al is Uranium Silicide-like structured and crystallizes in the hexagonal P6_3/mmc space group. Rh(1) is bonded to eight equivalent Rh(1) and four equivalent Al(1) atoms to form distorted RhAl4Rh8 cuboctahedra that share corners with four equivalent Al(1)Rh12 cuboctahedra, corners with fourteen equivalent Rh(1)Al4Rh8 cuboctahedra, edges with six equivalent Al(1)Rh12 cuboctahedra, edges with twelve equivalent Rh(1)Al4Rh8 cuboctahedra, faces with four equivalent Al(1)Rh12 cuboctahedra, and faces with sixteen equivalent Rh(1)Al4Rh8 cuboctahedra. Al(1) is bonded to twelve equivalent Rh(1) atoms to form AlRh12 cuboctahedra that share corners with six equivalent Al(1)Rh12 cuboctahedra, corners with twelve equivalent Rh(1)Al4Rh8 cuboctahedra, edges with eighteen equivalent Rh(1)Al4Rh8 cuboctahedra, faces with eight equivalent Al(1)Rh12 cuboctahedra, and faces with twelve equivalent Rh(1)Al4Rh8 cuboctahedra. is represented by the CIF card [CIF]
