Materials Data on Sb3(BrF8)2 by Materials Project

Abstract

Sb3F16(Br)2 crystallizes in the monoclinic C2/c space group. The structure is zero-dimensional and consists of eight hydrobromic acid molecules and four Sb3F16 clusters. In each Sb3F16 cluster, there are two inequivalent Sb2+ sites. In the first Sb2+ site, Sb2+ is bonded to six F1- atoms to form corner-sharing SbF6 octahedra. The corner-sharing octahedral tilt angles are 33°. There are a spread of Sb–F bond distances ranging from 1.89–2.14 Å. In the second Sb2+ site, Sb2+ is bonded to six F1- atoms to form corner-sharing SbF6 octahedra. The corner-sharing octahedral tilt angles are 33°. There is four shorter (1.89 Å) and two longer (2.02 Å) Sb–F bond length. There are eight inequivalent F1- sites. In the first F1- site, F1- is bonded in a single-bond geometry to one Sb2+ atom. In the second F1- site, F1- is bonded in a single-bond geometry to one Sb2+ atom. In the third F1- site, F1- is bonded in a single-bond geometry to one Sb2+ atom. In the fourth F1- site, F1- is bonded in a single-bond geometry to one Sb2+ atom. In the fifth F1- site, F1- is bonded in a single-bond geometry to one Sb2+ atom. In the sixth F1- site, F1- is bonded in a single-bond geometry to one Sb2+ atom. In the seventh F1- site, F1- is bonded in a single-bond geometry to one Sb2+ atom. In the eighth F1- site, F1- is bonded in a bent 150 degrees geometry to two Sb2+ atoms.
