Abstract

Xe2O4F3AsF6 crystallizes in the monoclinic P2_1/c space group. The structure is zero-dimensional and consists of four AsF6 clusters and four Xe2O4F3 clusters. In each AsF6 cluster, As is bonded in an octahedral geometry to six F atoms. There are a spread of As–F bond distances ranging from 1.74–1.80 Å. There are six inequivalent F sites. In the first F site, F is bonded in a single-bond geometry to one As atom. In the second F site, F is bonded in a single-bond geometry to one As atom. In the third F site, F is bonded in a single-bond geometry to one As atom. In the fourth F site, F is bonded in a single-bond geometry to one As atom. In the fifth F site, F is bonded in a single-bond geometry to one As atom. In the sixth F site, F is bonded in a single-bond geometry to one As atom. In each Xe2O4F3 cluster, there are two inequivalent Xe sites. In the first Xe site, Xe is bonded in a distorted see-saw-like geometry to two O and two F atoms. Both Xe–O bond lengths are 1.85 Å. There are one shorter (2.03 Å) and one longer (2.31 Å) Xe–F bond lengths. In the second Xe site, Xe is bonded in a distorted see-saw-like geometry to two O and two F atoms. Both Xe–O bond lengths are 1.85 Å. There are one shorter (2.04 Å) and one longer (2.28 Å) Xe–F bond lengths. There are four inequivalent O sites. In the first O site, O is bonded in a single-bond geometry to one Xe atom. In the second O site, O is bonded in a single-bond geometry to one Xe atom. In the third O site, O is bonded in a single-bond geometry to one Xe atom. In the fourth O site, O is bonded in a single-bond geometry to one Xe atom. 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 single-bond geometry to one Xe atom. In the third F site, F is bonded in a linear geometry to two Xe atoms.
