The crystal structure described by HfMnGe crystallizes in the hexagonal P-62m space group. Hf(1) is bonded in a 11-coordinate geometry to six equivalent Mn(1), one Ge(2), and four equivalent Ge(1) atoms. Mn(1) is bonded in a 4-coordinate geometry to six equivalent Hf(1), two equivalent Ge(1), and two equivalent Ge(2) atoms. There are two inequivalent Ge sites. In the first Ge site, Ge(2) is bonded in a 9-coordinate geometry to three equivalent Hf(1) and six equivalent Mn(1) atoms. In the second Ge site, Ge(1) is bonded in a 9-coordinate geometry to six equivalent Hf(1) and three equivalent Mn(1) atoms. is represented by the CIF card [CIF]
