Materials Data on AsXeO2F7 by Materials Project
XeO2FAsF6 crystallizes in the orthorhombic P2_12_12_1 space group. The structure is zero-dimensional and consists of four AsF6 clusters and four XeO2F 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 1.74–1.82 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 XeO2F cluster, Xe is bonded in a distorted trigonal non-coplanar geometry to two O and one F atom. Both Xe–O bond lengths are 1.84 Å. The Xe–F bond length is 2.03 Å. There are two 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. F is bonded in a single-bond geometry to one Xe atom.
