Title: Materials Data on Hf3GeO8 by Materials Project

Abstract

Hf3GeO8 crystallizes in the tetragonal I-42m space group. The structure is three-dimensional. there are two inequivalent Hf4+ sites. In the first Hf4+ site, Hf4+ is bonded in a distorted body-centered cubic geometry to eight O2- atoms. There are four shorter (2.04 Å) and four longer (2.45 Å) Hf–O bond lengths. In the second Hf4+ site, Hf4+ is bonded in a 8-coordinate geometry to eight O2- atoms. There are four shorter (2.18 Å) and four longer (2.22 Å) Hf–O bond lengths. Ge4+ is bonded in a tetrahedral geometry to four equivalent O2- atoms. All Ge–O bond lengths are 1.79 Å. There are two inequivalent O2- sites. In the first O2- site, O2- is bonded in a trigonal planar geometry to three Hf4+ atoms. In the second O2- site, O2- is bonded in a 4-coordinate geometry to three Hf4+ and one Ge4+ atom.
