PI3 is Upper Bainite structured and crystallizes in the hexagonal P6_3 space group. The structure is zero-dimensional and consists of two phosphorus triiodide molecules. P(1) is bonded in a trigonal non-coplanar geometry to three equivalent I(1) atoms. I(1) is bonded in a single-bond geometry to one P(1) atom.
