Abstract

XeF5GeF5 crystallizes in the orthorhombic Pnma space group. The structure is one-dimensional and consists of four XeF5 clusters and two GeF5 ribbons oriented in the (1, 0, 0) direction. In each XeF5 cluster, Xe is bonded in a distorted square pyramidal geometry to five F atoms. There is one shorter (1.97 Å) and four longer (1.98 Å) Xe–F bond length. There are four 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 single-bond geometry to one Xe atom. In the fourth F site, F is bonded in a single-bond geometry to one Xe atom. In each GeF5 ribbon, Ge is bonded to six F atoms to form corner-sharing GeF6 octahedra. The corner-sharing octahedral tilt angles are 42°. There are a spread of Ge–F bond distances ranging from 1.79–1.94 Å. There are three inequivalent F sites. In the first F site, F is bonded in a single-bond geometry to one Ge atom. In the second F site, F is bonded in a single-bond geometry to one Ge atom. In the third F site, F is bonded in a bent 150 degrees geometry to two equivalent Ge atoms.
