The compound described by RuIr is Magnesium-derived structured and crystallizes in the hexagonal P-6m2 space group. Ru(1) is bonded to six equivalent Ru(1) and six equivalent Ir(1) atoms to form RuIr6Ru6 cuboctahedra that share corners with eighteen equivalent Ru(1)Ir6Ru6 cuboctahedra, edges with six equivalent Ru(1)Ir6Ru6 cuboctahedra, edges with twelve equivalent Ir(1)Ir6Ru6 cuboctahedra, faces with eight equivalent Ru(1)Ir6Ru6 cuboctahedra, and faces with twelve equivalent Ir(1)Ir6Ru6 cuboctahedra. Ir(1) is bonded to six equivalent Ru(1) and six equivalent Ir(1) atoms to form IrIr6Ru6 cuboctahedra that share corners with eighteen equivalent Ir(1)Ir6Ru6 cuboctahedra, edges with six equivalent Ir(1)Ir6Ru6 cuboctahedra, edges with twelve equivalent Ru(1)Ir6Ru6 cuboctahedra, faces with eight equivalent Ir(1)Ir6Ru6 cuboctahedra, and faces with twelve equivalent Ru(1)Ir6Ru6 cuboctahedra. is represented by the Crystallographic Information File (CIF) [CIF]
