Materials Data on ReOF4 by Materials Project

ReOF4 crystallizes in the monoclinic C2/c space group. The structure is one-dimensional and consists of eight ReOF4 ribbons oriented in the (0, 1, 0) direction. there are two inequivalent Re6+ sites. In the first Re6+ site, Re6+ is bonded in a 6-coordinate geometry to one O2- and five F1- atoms. The Re–O bond length is 1.68 Å. There are a spread of Re–F bond distances ranging from 1.88–2.36 Å. In the second Re6+ site, Re6+ is bonded in a 6-coordinate geometry to one O2- and five F1- atoms. The Re–O bond length is 1.68 Å. There are a spread of Re–F bond distances ranging from 1.88–2.38 Å. There are two inequivalent O2- sites. In the first O2- site, O2- is bonded in a single-bond geometry to one Re6+ atom. In the second O2- site, O2- is bonded in a single-bond geometry to one Re6+ atom. There are eight inequivalent F1- sites. In the first F1- site, F1- is bonded in a single-bond geometry to one Re6+ atom. In the second F1- site, F1- is bonded in a 2-coordinate geometry to two Re6+ atoms. In the third F1- site, F1- is bonded in a single-bond geometry to one Re6+ atom. In the fourth F1- site, F1- is bonded in a distorted bent 150 degrees geometry to two Re6+ atoms. In the fifth F1- site, F1- is bonded in a single-bond geometry to one Re6+ atom. In the sixth F1- site, F1- is bonded in a single-bond geometry to one Re6+ atom. In the seventh F1- site, F1- is bonded in a single-bond geometry to one Re6+ atom. In the eighth F1- site, F1- is bonded in a single-bond geometry to one Re6+ atom.
