Materials Data on Ge(BrF5)2 by Materials Project

Abstract

Ge(BrF5)2 crystallizes in the monoclinic P2_1/c space group. The structure is one-dimensional and consists of two Ge(BrF5)2 ribbons oriented in the (1, 0, 0) direction. Ge is bonded in an octahedral geometry to six F atoms. There is two shorter (1.76 Å) and four longer (1.89 Å) Ge–F bond length. Br is bonded in a rectangular see-saw-like geometry to four F atoms. There are a spread of Br–F bond distances ranging from 1.78–2.20 Å. There are five inequivalent F sites. In the first F site, F is bonded in a single-bond geometry to one Br atom. In the second F site, F is bonded in a single-bond geometry to one Br atom. In the third F site, F is bonded in a distorted bent 120 degrees geometry to one Ge and one Br atom. In the fourth F site, F is bonded in a distorted bent 120 degrees geometry to one Ge and one Br atom. In the fifth F site, F is bonded in a single-bond geometry to one Ge atom.
