Materials Data on CsXeF7 by Materials Project
XeCsF7 crystallizes in the cubic P2_13 space group. The structure is three-dimensional. Xe is bonded in a 7-coordinate geometry to seven F atoms. There are a spread of Xe–F bond distances ranging from 2.06–2.14 Å. Cs is bonded in a 9-coordinate geometry to fifteen F atoms. There are a spread of Cs–F bond distances ranging from 3.19–3.59 Å. There are three inequivalent F sites. In the first F site, F is bonded in a distorted single-bond geometry to one Xe and two equivalent Cs atoms. In the second F site, F is bonded in a distorted single-bond geometry to one Xe and two equivalent Cs atoms. In the third F site, F is bonded in a distorted single-bond geometry to one Xe and three equivalent Cs atoms.
