Materials Data on Sb4Xe2F19 by Materials Project

Abstract

(Xe)2Sb4F19 crystallizes in the monoclinic P2_1/c space group. The structure is zero-dimensional and consists of four xenon molecules and two Sb4F19 clusters. In each Sb4F19 cluster, there are two inequivalent Sb sites. In the first Sb site, Sb is bonded to six F atoms to form SbF6 octahedra that share a cornercorner with one SbF6 octahedra and a cornercorner with one SbF5 trigonal bipyramid. The corner-sharing octahedral tilt angles are 0°. There are a spread of Sb–F bond distances ranging from 1.88–2.09 Å. In the second Sb site, Sb is bonded to five F atoms to form distorted corner-sharing SbF5 trigonal bipyramids. The corner-sharing octahedral tilt angles are 35°. There are a spread of Sb–F bond distances ranging from 1.89–2.21 Å. There are ten 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 linear geometry to two equivalent Sb atoms. 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 the seventh F site, F is bonded in a single-bond geometry to one Sb atom. In the eighth F site, F is bonded in a single-bond geometry to one Sb atom. In the ninth F site, F is bonded in a single-bond geometry to one Sb atom. In the tenth F site, F is bonded in a bent 150 degrees geometry to two Sb atoms.
