Materials Data on AuXeF9 by Materials Project
XeF5AuF4 crystallizes in the tetragonal I4/m space group. The structure is zero-dimensional and consists of four AuF4 clusters and four XeF5 clusters. In each AuF4 cluster, Au is bonded in a square co-planar geometry to four equivalent F atoms. All Au–F bond lengths are 1.97 Å. F is bonded in a single-bond geometry to one Au atom. In each XeF5 cluster, Xe is bonded in a distorted square pyramidal geometry to five F atoms. All Xe–F bond lengths are 1.99 Å. There are two 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.
