Materials Data on Sb2XeF15 by Materials Project

Abstract

XeF4Sb2F11 crystallizes in the monoclinic C2/c space group. The structure is zero-dimensional and consists of four Sb2F11 clusters and four XeF4 clusters. In each Sb2F11 cluster, Sb is bonded to six F atoms to form corner-sharing SbF6 octahedra. The corner-sharing octahedral tilt angles are 0°. There are a spread of Sb–F bond distances ranging from 1.89–2.08 Å. There are six inequivalent F sites. In the first F site, F is bonded in a linear geometry to two equivalent Sb atoms. In the second F site, F is bonded in a single-bond geometry to one Sb atom. In the third F site, F is bonded in a single-bond geometry to one Sb atom. In the fourth F site, F is bonded in a single-bond geometry to one Sb atom. In the fifth F site, F is bonded in a single-bond geometry to one Sb atom. In the sixth F site, F is bonded in a single-bond geometry to one Sb atom. In each XeF4 cluster, Xe is bonded in a square co-planar geometry to four F atoms. There are two shorter (2.00 Å) and two longer (2.02 Å) Xe–F bond lengths. There are two inequivalent F sites. In the first F site, F is bonded in a single-bond geometry to one Xe atom. In the second F site, F is bonded in a single-bond geometry to one Xe atom.
