Materials Data on AsXe2BrOF12 by Materials Project
Xe2OBrF6AsF6 is alpha carbon monoxide-like structured and crystallizes in the monoclinic P2_1/c space group. The structure is zero-dimensional and consists of four AsF6 clusters and four Xe2OBrF6 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 1.76–1.81 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 Xe2OBrF6 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 (2.05 Å) and one longer (2.15 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 (2.04 Å) and one longer (2.15 Å) Xe–F bond lengths. O is bonded in a single-bond geometry to one Br atom. The O–Br bond length is 1.59 Å. Br is bonded in a distorted square pyramidal geometry to one O and four F atoms. There are a spread of Br–F bond distances ranging from 1.80–2.32 Å. There are six 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 Br atom. In the third F site, F is bonded in a distorted bent 150 degrees geometry to one Xe and one Br atom. In the fourth F site, F is bonded in a bent 150 degrees geometry to one Xe and one Br atom. In the fifth F site, F is bonded in a single-bond geometry to one Xe atom. In the sixth F site, F is bonded in a single-bond geometry to one Br atom.
