Materials Data on AuBrF6 by Materials Project
AuBrF6 crystallizes in the monoclinic P2_1 space group. The structure is one-dimensional and consists of two AuBrF6 ribbons oriented in the (0, 1, 0) direction. Au1+ is bonded in a rectangular see-saw-like geometry to four F1- atoms. There is two shorter (1.94 Å) and two longer (2.02 Å) Au–F bond length. Br5+ is bonded in a rectangular see-saw-like geometry to four F1- atoms. There are a spread of Br–F bond distances ranging from 1.79–2.16 Å. There are six 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 Au1+ atom. In the fourth F1- site, F1- is bonded in a single-bond geometry to one Au1+ atom. In the fifth F1- site, F1- is bonded in a distorted bent 120 degrees geometry to one Au1+ and one Br5+ atom. In the sixth F1- site, F1- is bonded in a bent 120 degrees geometry to one Au1+ and one Br5+ atom.
