Materials Data on SbF5 by Materials Project

Abstract

SbF5 crystallizes in the orthorhombic Immm space group. The structure is two-dimensional and consists of two SbF5 sheets oriented in the (0, 0, 1) direction. Sb5+ is bonded to eight F1- atoms to form a mixture of distorted edge and corner-sharing SbF8 hexagonal bipyramids. There are a spread of Sb–F bond distances ranging from 1.88–2.29 Å. There are three inequivalent F1- sites. In the first F1- site, F1- is bonded in a bent 120 degrees geometry to two equivalent Sb5+ atoms. In the second F1- site, F1- is bonded in a single-bond geometry to one Sb5+ atom. In the third F1- site, F1- is bonded in a distorted linear geometry to two equivalent Sb5+ atoms.
