BI3 is Indium-like structured and crystallizes in the hexagonal P6_3/m space group. The structure is zero-dimensional and consists of two boron triiodide molecules. B(1) is bonded in a trigonal planar geometry to three equivalent I(1) atoms. I(1) is bonded in a single-bond geometry to one B(1) atom.
