Materials Data on PBr3 by Materials Project
PBr3 is Ammonia-like structured and crystallizes in the orthorhombic Pnma space group. The structure is zero-dimensional and consists of four phosphorus tribromide molecules. P3+ is bonded in a trigonal non-coplanar geometry to three Br1- atoms. All P–Br bond lengths are 2.25 Å. There are two inequivalent Br1- sites. In the first Br1- site, Br1- is bonded in a single-bond geometry to one P3+ atom. In the second Br1- site, Br1- is bonded in a single-bond geometry to one P3+ atom.
