Materials Data on Ge5F12 by Materials Project
Ge5F12 crystallizes in the monoclinic P2_1/c space group. The structure is three-dimensional. there are three inequivalent Ge+2.40+ sites. In the first Ge+2.40+ site, Ge+2.40+ is bonded in a 4-coordinate geometry to four F1- atoms. There are a spread of Ge–F bond distances ranging from 1.87–2.45 Å. In the second Ge+2.40+ site, Ge+2.40+ is bonded in an octahedral geometry to six F1- atoms. There are a spread of Ge–F bond distances ranging from 1.79–1.88 Å. In the third Ge+2.40+ site, Ge+2.40+ is bonded in a rectangular see-saw-like geometry to four F1- atoms. There are a spread of Ge–F bond distances ranging from 1.84–2.35 Å. There are six inequivalent F1- sites. In the first F1- site, F1- is bonded in a distorted linear geometry to two Ge+2.40+ atoms. In the second F1- site, F1- is bonded in a single-bond geometry to one Ge+2.40+ atom. In the third F1- site, F1- is bonded in a 2-coordinate geometry to two Ge+2.40+ atoms. In the fourth F1- site, F1- is bonded in a distorted bent 120 degrees geometry to two Ge+2.40+ atoms. In the fifth F1- site, F1- is bonded in a distorted bent 150 degrees geometry to two Ge+2.40+ atoms. In the sixth F1- site, F1- is bonded in a distorted bent 120 degrees geometry to two Ge+2.40+ atoms.
