The compound described by Hf3Ge2 crystallizes in the tetragonal P4/mbm space group. There are two inequivalent Hf sites. In the first Hf site, Hf(1) is bonded in a square co-planar geometry to four equivalent Ge(1) atoms. In the second Hf site, Hf(2) is bonded in a 6-coordinate geometry to six equivalent Ge(1) atoms. Ge(1) is bonded in a 9-coordinate geometry to two equivalent Hf(1), six equivalent Hf(2), and one Ge(1) atom. is represented by the CIF card [CIF]
