Materials Data on BCl3 by Materials Project
BCl3 crystallizes in the hexagonal P6_3/m space group. The structure is zero-dimensional and consists of two boron trichloride molecules. B3+ is bonded in a trigonal planar geometry to three equivalent Cl1- atoms. All B–Cl bond lengths are 1.74 Å. Cl1- is bonded in a single-bond geometry to one B3+ atom.
