HfGeS is Matlockite structured and crystallizes in the tetragonal P4/nmm space group. Hf(1) is bonded in a 9-coordinate geometry to four equivalent Ge(1) and five equivalent S(1) atoms. Ge(1) is bonded in a 8-coordinate geometry to four equivalent Hf(1) and four equivalent Ge(1) atoms. S(1) is bonded to five equivalent Hf(1) atoms to form a mixture of distorted corner and edge-sharing SHf5 trigonal bipyramids.
HfGeS is Matlockite structured and crystallizes in the tetragonal P4/nmm space group. Hf(1) is bonded in a 9-coordinate geometry to four equivalent Ge(1) and five equivalent S(1) atoms. All Hf(1)-Ge(1) bond lengths are 2.83 Å. There are four shorter (2.69 Å) and one longer (2.75 Å) Hf(1)-S(1) bond length. Ge(1) is bonded in a 8-coordinate geometry to four equivalent Hf(1) and four equivalent Ge(1) atoms. All Ge(1)-Ge(1) bond lengths are 2.55 Å. S(1) is bonded to five equivalent Hf(1) atoms to form a mixture of distorted corner and edge-sharing SHf5 trigonal bipyramids.
