Materials Data on Hf3Ge by Materials Project

Abstract

Hf3Ge crystallizes in the tetragonal P4_2/n space group. The structure is three-dimensional. there are three inequivalent Hf sites. In the first Hf site, Hf is bonded in a 3-coordinate geometry to three equivalent Ge atoms. There are a spread of Hf–Ge bond distances ranging from 2.76–2.94 Å. In the second Hf site, Hf is bonded in a distorted see-saw-like geometry to four equivalent Ge atoms. There are a spread of Hf–Ge bond distances ranging from 2.77–2.83 Å. In the third Hf site, Hf is bonded in a distorted bent 150 degrees geometry to two equivalent Ge atoms. There are one shorter (2.78 Å) and one longer (2.84 Å) Hf–Ge bond lengths. Ge is bonded in a 9-coordinate geometry to nine Hf atoms.
