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.
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. All Hf(1)-Cu(1) bond lengths are 2.95 Å. There are four shorter (2.72 Å) and one longer (2.73 Å) Hf(1)-Ge(1) bond length.
