Materials Data on PCl3 by Materials Project
PCl3 is Ammonia-like structured and crystallizes in the orthorhombic Pnma space group. The structure is zero-dimensional and consists of four phosphorus trichloride molecules. P3+ is bonded in a trigonal non-coplanar geometry to three Cl1- atoms. All P–Cl bond lengths are 2.07 Å. There are two inequivalent Cl1- sites. In the first Cl1- site, Cl1- is bonded in a single-bond geometry to one P3+ atom. In the second Cl1- site, Cl1- is bonded in a single-bond geometry to one P3+ atom.
