The compound described by HfCuGe crystallizes in the tetragonal I4/mmm space group. Hf(1) is bonded in a 9-coordinate geometry to four equivalent Cu(1) and five equivalent Ge(1) atoms. Cu(1) is bonded to four equivalent Hf(1), four equivalent Cu(1), and four equivalent Ge(1) atoms to form a mixture of face and corner-sharing CuHf4Cu4Ge4 cuboctahedra. Ge(1) is bonded in a 9-coordinate geometry to five equivalent Hf(1) and four equivalent Cu(1) atoms. is represented by the CIF file [CIF]
