The material described by Ru3Rh is beta Cu3Ti-like structured and crystallizes in the hexagonal P6_3/mmc space group. Ru(1) is bonded to eight equivalent Ru(1) and four equivalent Rh(1) atoms to form RuRu8Rh4 cuboctahedra that share corners with four equivalent Rh(1)Ru12 cuboctahedra, corners with fourteen equivalent Ru(1)Ru8Rh4 cuboctahedra, edges with six equivalent Rh(1)Ru12 cuboctahedra, edges with twelve equivalent Ru(1)Ru8Rh4 cuboctahedra, faces with four equivalent Rh(1)Ru12 cuboctahedra, and faces with sixteen equivalent Ru(1)Ru8Rh4 cuboctahedra. Rh(1) is bonded to twelve equivalent Ru(1) atoms to form RhRu12 cuboctahedra that share corners with six equivalent Rh(1)Ru12 cuboctahedra, corners with twelve equivalent Ru(1)Ru8Rh4 cuboctahedra, edges with eighteen equivalent Ru(1)Ru8Rh4 cuboctahedra, faces with eight equivalent Rh(1)Ru12 cuboctahedra, and faces with twelve equivalent Ru(1)Ru8Rh4 cuboctahedra. is represented by the CIF card [CIF]
