The material described by NiRh crystallizes in the trigonal R-3m space group. Rh(1) is bonded to six equivalent Rh(1) and six equivalent Ni(1) atoms to form distorted RhNi6Rh6 cuboctahedra that share corners with twelve equivalent Rh(1)Ni6Rh6 cuboctahedra, edges with twelve equivalent Rh(1)Ni6Rh6 cuboctahedra, edges with twelve equivalent Ni(1)Ni6Rh6 cuboctahedra, faces with six equivalent Rh(1)Ni6Rh6 cuboctahedra, and faces with twelve equivalent Ni(1)Ni6Rh6 cuboctahedra.
