CrRu crystallizes in the hexagonal P-6m2 space group. Cr(1) is bonded to six equivalent Cr(1) and six equivalent Ru(1) atoms to form distorted CrCr6Ru6 cuboctahedra that share corners with eighteen equivalent Cr(1)Cr6Ru6 cuboctahedra, edges with six equivalent Cr(1)Cr6Ru6 cuboctahedra, edges with twelve equivalent Ru(1)Cr6Ru6 cuboctahedra, faces with eight equivalent Cr(1)Cr6Ru6 cuboctahedra, and faces with twelve equivalent Ru(1)Cr6Ru6 cuboctahedra. Ru(1) is bonded to six equivalent Cr(1) and six equivalent Ru(1) atoms to form distorted RuCr6Ru6 cuboctahedra that share corners with eighteen equivalent Ru(1)Cr6Ru6 cuboctahedra, edges with six equivalent Ru(1)Cr6Ru6 cuboctahedra, edges with twelve equivalent Cr(1)Cr6Ru6 cuboctahedra, faces with eight equivalent Ru(1)Cr6Ru6 cuboctahedra, and faces with twelve equivalent Cr(1)Cr6Ru6 cuboctahedra.
