The structure described by HfGe2 is Zirconium Disilicide structured and crystallizes in the orthorhombic Cmcm space group. Hf(1) is bonded in a 10-coordinate geometry to four equivalent Ge(2) and six equivalent Ge(1) atoms. There are two inequivalent Ge sites. In the first Ge site, Ge(1) is bonded in a 8-coordinate geometry to six equivalent Hf(1) and two equivalent Ge(1) atoms. In the second Ge site, Ge(2) is bonded in a 8-coordinate geometry to four equivalent Hf(1) and four equivalent Ge(2) atoms. is represented by the CIF card [CIF]
