The material described by Co4Ge crystallizes in the trigonal R-3m space group. There are four inequivalent Co sites. In the first Co site, Co(1) is bonded to three equivalent Co(2), six equivalent Co(1), and three equivalent Ge(1) atoms to form CoCo9Ge3 cuboctahedra that share corners with three equivalent Co(2)Co12 cuboctahedra, corners with nine equivalent Co(1)Co9Ge3 cuboctahedra, edges with six equivalent Ge(1)Co6Ge6 cuboctahedra, edges with nine equivalent Co(2)Co12 cuboctahedra, edges with nine equivalent Co(1)Co9Ge3 cuboctahedra, faces with six equivalent Co(2)Co12 cuboctahedra, faces with six equivalent Co(1)Co9Ge3 cuboctahedra, and faces with six equivalent Ge(1)Co6Ge6 cuboctahedra. In the second Co site, Co(2) is bonded to three equivalent Co(1) and nine equivalent Co(2) atoms to form CoCo12 cuboctahedra that share corners with three equivalent Co(1)Co9Ge3 cuboctahedra, corners with three equivalent Ge(1)Co6Ge6 cuboctahedra, corners with six equivalent Co(2)Co12 cuboctahedra, edges with three equivalent Ge(1)Co6Ge6 cuboctahedra, edges with nine equivalent Co(1)Co9Ge3 cuboctahedra, edges with twelve equivalent Co(2)Co12 cuboctahedra, faces with six equivalent Co(1)Co9Ge3 cuboctahedra, and faces with twelve equivalent Co(2)Co12 cuboctahedra.
