Materials Data on SbXe2F9 by Materials Project

Abstract

Xe2F3SbF6 crystallizes in the monoclinic Cc space group. The structure is zero-dimensional and consists of four SbF6 clusters and four Xe2F3 clusters. In each SbF6 cluster, Sb is bonded in an octahedral geometry to six F atoms. There is three shorter (1.92 Å) and three longer (1.93 Å) Sb–F bond length. There are six inequivalent F sites. In the first F site, F is bonded in a single-bond geometry to one Sb atom. 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 Xe2F3 cluster, there are two inequivalent Xe sites. In the first Xe site, Xe is bonded in a linear geometry to two F atoms. There are one shorter (2.01 Å) and one longer (2.22 Å) Xe–F bond lengths. In the second Xe site, Xe is bonded in a linear geometry to two F atoms. There are one shorter (2.01 Å) and one longer (2.21 Å) Xe–F bond lengths. There are three 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 bent 150 degrees geometry to two Xe atoms. In the third F site, F is bonded in a single-bond geometry to one Xe atom.
