Materials Data on TeBrO3F5 by Materials Project
TeO3BrF5 crystallizes in the monoclinic P2_1/c space group. The structure is zero-dimensional and consists of four TeO3BrF5 clusters. Te6+ is bonded in an octahedral geometry to one O2- and five F1- atoms. The Te–O bond length is 1.92 Å. There are a spread of Te–F bond distances ranging from 1.87–1.89 Å. There are three inequivalent O2- sites. In the first O2- site, O2- is bonded in a single-bond geometry to one Br5+ atom. The O–Br bond length is 1.63 Å. In the second O2- site, O2- is bonded in a distorted bent 120 degrees geometry to one Te6+ and one Br5+ atom. The O–Br bond length is 2.01 Å. In the third O2- site, O2- is bonded in a single-bond geometry to one Br5+ atom. The O–Br bond length is 1.63 Å. Br5+ is bonded in a trigonal non-coplanar geometry to three O2- atoms. There are five inequivalent F1- sites. In the first F1- site, F1- is bonded in a single-bond geometry to one Te6+ atom. In the second F1- site, F1- is bonded in a single-bond geometry to one Te6+ atom. In the third F1- site, F1- is bonded in a single-bond geometry to one Te6+ atom. In the fourth F1- site, F1- is bonded in a single-bond geometry to one Te6+ atom. In the fifth F1- site, F1- is bonded in a single-bond geometry to one Te6+ atom.
