Materials Data on Re4Xe3(O5F7)2 by Materials Project

Abstract

Xe3Re4(O5F7)2 crystallizes in the triclinic P-1 space group. The structure is zero-dimensional and consists of one Xe3Re4(O5F7)2 cluster. there are two inequivalent Xe sites. In the first Xe site, Xe is bonded in a linear geometry to two equivalent O atoms. Both Xe–O bond lengths are 2.22 Å. In the second Xe site, Xe is bonded in a linear geometry to one O and one F atom. The Xe–O bond length is 2.06 Å. The Xe–F bond length is 2.43 Å. There are two inequivalent Re sites. In the first Re site, Re is bonded to two O and four F atoms to form distorted corner-sharing ReO2F4 octahedra. The corner-sharing octahedral tilt angles are 21°. There is one shorter (1.71 Å) and one longer (1.72 Å) Re–O bond length. There are a spread of Re–F bond distances ranging from 1.88–2.08 Å. In the second Re site, Re is bonded to two O and four F atoms to form distorted corner-sharing ReO2F4 octahedra. The corner-sharing octahedral tilt angles are 21°. There is one shorter (1.70 Å) and one longer (1.72 Å) Re–O bond length. There are a spread of Re–F bond distances ranging from 1.89–2.28 Å. There are five inequivalent O sites. In the first O site, O is bonded in a single-bond geometry to one Re atom. In the second O site, O is bonded in a single-bond geometry to one Re atom. In the third O site, O is bonded in a single-bond geometry to one Re atom. In the fourth O site, O is bonded in a bent 120 degrees geometry to two Xe atoms. In the fifth O site, O is bonded in a single-bond geometry to one Re atom. There are seven inequivalent F sites. In the first F site, F is bonded in a distorted bent 150 degrees geometry to one Xe and one Re atom. In the second F site, F is bonded in a bent 150 degrees geometry to two Re atoms. In the third F site, F is bonded in a single-bond geometry to one Re atom. In the fourth F site, F is bonded in a single-bond geometry to one Re atom. In the fifth F site, F is bonded in a single-bond geometry to one Re atom. In the sixth F site, F is bonded in a single-bond geometry to one Re atom. In the seventh F site, F is bonded in a single-bond geometry to one Re atom.
