Materials Data on SbCl3F2 by Materials Project

Abstract

SbCl3F2 crystallizes in the tetragonal I4 space group. The structure is zero-dimensional and consists of two SbCl3F2 clusters. Sb5+ is bonded to three Cl1- and three F1- atoms to form distorted corner-sharing SbCl3F3 octahedra. The corner-sharing octahedral tilt angles are 11°. There are two shorter (2.32 Å) and one longer (2.33 Å) Sb–Cl bond lengths. There are a spread of Sb–F bond distances ranging from 1.91–2.13 Å. There are three inequivalent Cl1- sites. In the first Cl1- site, Cl1- is bonded in a single-bond geometry to one Sb5+ atom. In the second Cl1- site, Cl1- is bonded in a distorted single-bond geometry to one Sb5+ atom. In the third Cl1- site, Cl1- is bonded in a single-bond geometry to one Sb5+ atom. There are two inequivalent F1- sites. In the first F1- site, F1- is bonded in a single-bond geometry to one Sb5+ atom. In the second F1- site, F1- is bonded in a linear geometry to two equivalent Sb5+ atoms.
