The structure described by Hf4Co7Ge6 crystallizes in the cubic Im-3m space group. Hf(1) is bonded to six equivalent Co(1) and six equivalent Ge(1) atoms to form HfCo6Ge6 cuboctahedra that share corners with twelve equivalent Hf(1)Co6Ge6 cuboctahedra, faces with six equivalent Hf(1)Co6Ge6 cuboctahedra, and faces with two equivalent Co(2)Ge6 octahedra. There are two inequivalent Co sites. In the first Co site, Co(1) is bonded in a 8-coordinate geometry to four equivalent Hf(1) and four equivalent Ge(1) atoms. In the second Co site, Co(2) is bonded to six equivalent Ge(1) atoms to form CoGe6 octahedra that share faces with eight equivalent Hf(1)Co6Ge6 cuboctahedra. Ge(1) is bonded in a 9-coordinate geometry to four equivalent Hf(1), one Co(2), and four equivalent Co(1) atoms. is represented by the CIF card [CIF]
