Materials Data on Ge3F8 by Materials Project

Abstract

Ge3F8 crystallizes in the monoclinic P2_1/c space group. The structure is two-dimensional and consists of one Ge3F8 sheet oriented in the (-1, 0, 2) direction. there are two inequivalent Ge+2.67+ sites. In the first Ge+2.67+ site, Ge+2.67+ is bonded in a 4-coordinate geometry to three F1- atoms. There are a spread of Ge–F bond distances ranging from 1.98–2.04 Å. In the second Ge+2.67+ site, Ge+2.67+ is bonded in an octahedral geometry to six F1- atoms. There are a spread of Ge–F bond distances ranging from 1.80–1.90 Å. There are four inequivalent F1- sites. In the first F1- site, F1- is bonded in a bent 150 degrees geometry to two Ge+2.67+ atoms. In the second F1- site, F1- is bonded in a single-bond geometry to one Ge+2.67+ atom. In the third F1- site, F1- is bonded in a distorted single-bond geometry to one Ge+2.67+ atom. In the fourth F1- site, F1- is bonded in a bent 150 degrees geometry to two equivalent Ge+2.67+ atoms.
