FeRu crystallizes in the hexagonal P-6m2 space group. Ru(1) is bonded to six equivalent Ru(1) and six equivalent Fe(1) atoms to form distorted RuFe6Ru6 cuboctahedra that share corners with eighteen equivalent Ru(1)Fe6Ru6 cuboctahedra, edges with six equivalent Ru(1)Fe6Ru6 cuboctahedra, edges with twelve equivalent Fe(1)Fe6Ru6 cuboctahedra, faces with eight equivalent Ru(1)Fe6Ru6 cuboctahedra, and faces with twelve equivalent Fe(1)Fe6Ru6 cuboctahedra. Fe(1) is bonded to six equivalent Ru(1) and six equivalent Fe(1) atoms to form distorted FeFe6Ru6 cuboctahedra that share corners with eighteen equivalent Fe(1)Fe6Ru6 cuboctahedra, edges with six equivalent Fe(1)Fe6Ru6 cuboctahedra, edges with twelve equivalent Ru(1)Fe6Ru6 cuboctahedra, faces with eight equivalent Fe(1)Fe6Ru6 cuboctahedra, and faces with twelve equivalent Ru(1)Fe6Ru6 cuboctahedra.
