Materials Data on BrF3 by Materials Project

BrF3 crystallizes in the orthorhombic Cmc2_1 space group. The structure is one-dimensional and consists of two BrF3 ribbons oriented in the (0, 0, 1) direction. Br is bonded in a rectangular see-saw-like geometry to four F atoms. There are a spread of Br–F bond distances ranging from 1.80–2.20 Å. There are three inequivalent F sites. In the first F site, F is bonded in a single-bond geometry to one Br atom. In the second F site, F is bonded in a bent 150 degrees geometry to two equivalent Br atoms. In the third F site, F is bonded in a single-bond geometry to one Br atom.

Materials Data on BrF5 by Materials Project

BrF5 crystallizes in the orthorhombic Cmc2_1 space group. The structure is zero-dimensional and consists of four BrF5 clusters. Br5+ is bonded in a square pyramidal geometry to five F1- atoms. There are a spread of Br–F bond distances ranging from 1.75–1.86 Å. There are four inequivalent F1- sites. In the first F1- site, F1- is bonded in a single-bond geometry to one Br5+ atom. In the second F1- site, F1- is bonded in a single-bond geometry to one Br5+ atom. In the third F1- site, F1- is bonded in a single-bond geometry to one Br5+ atom. In the fourth F1- site, F1- is bonded in a single-bond geometry to one Br5+ atom.
