The compound described by 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. is represented by the Crystallographic Information File (CIF) [CIF]
