The material structure described by RuRh4 is alpha La-derived structured and crystallizes in the trigonal R-3m space group. Ru(1) is bonded to six equivalent Ru(1) and six equivalent Rh(1) atoms to form RuRu6Rh6 cuboctahedra that share corners with six equivalent Ru(1)Ru6Rh6 cuboctahedra; corners with six Rh(2,2)Rh12 cuboctahedra; edges with six equivalent Ru(1)Ru6Rh6 cuboctahedra; edges with six Rh(2,2)Rh12 cuboctahedra; edges with twelve equivalent Rh(1)Ru3Rh9 cuboctahedra; faces with six equivalent Ru(1)Ru6Rh6 cuboctahedra; and faces with twelve equivalent Rh(1)Ru3Rh9 cuboctahedra. There are four inequivalent Rh sites. In the first Rh site, Rh(1) is bonded to three equivalent Ru(1), three equivalent Rh(2), and six equivalent Rh(1) atoms to form RhRu3Rh9 cuboctahedra that share corners with three equivalent Rh(2)Rh12 cuboctahedra; corners with nine equivalent Rh(1)Ru3Rh9 cuboctahedra; edges with six equivalent Ru(1)Ru6Rh6 cuboctahedra; edges with nine Rh(2,2)Rh12 cuboctahedra; edges with nine equivalent Rh(1)Ru3Rh9 cuboctahedra; faces with six equivalent Ru(1)Ru6Rh6 cuboctahedra; faces with six equivalent Rh(2)Rh12 cuboctahedra; and faces with six equivalent Rh(1)Ru3Rh9 cuboctahedra. In the second Rh site, Rh(2) is bonded to three equivalent Rh(1) and nine Rh(2,2) atoms to form RhRh12 cuboctahedra that share corners with three equivalent Ru(1)Ru6Rh6 cuboctahedra; corners with three equivalent Rh(1)Ru3Rh9 cuboctahedra; corners with six equivalent Rh(2)Rh12 cuboctahedra; edges with three equivalent Ru(1)Ru6Rh6 cuboctahedra; edges with nine equivalent Rh(1)Ru3Rh9 cuboctahedra; edges with twelve Rh(2,2)Rh12 cuboctahedra; faces with six equivalent Rh(1)Ru3Rh9 cuboctahedra; and faces with twelve Rh(2,2)Rh12 cuboctahedra.
