Materials Data on SbBrF8 by Materials Project
SbBrF8 crystallizes in the orthorhombic Pcca space group. The structure is one-dimensional and consists of two SbBrF8 ribbons oriented in the (0, 1, 0) direction. Sb3+ is bonded in an octahedral geometry to six F1- atoms. There is four shorter (1.90 Å) and two longer (1.99 Å) Sb–F bond length. Br5+ is bonded in a square co-planar geometry to four F1- atoms. There are two shorter (1.77 Å) and two longer (2.25 Å) Br–F bond lengths. There are four inequivalent F1- sites. In the first F1- site, F1- is bonded in a single-bond geometry to one Sb3+ atom. In the second F1- site, F1- is bonded in a single-bond geometry to one Sb3+ atom. In the third F1- site, F1- is bonded in a distorted bent 150 degrees geometry to one Sb3+ and one Br5+ atom. In the fourth F1- site, F1- is bonded in a single-bond geometry to one Br5+ atom.
