The compound described by PI2 is Indium-like structured and crystallizes in the triclinic P-1 space group. The structure is zero-dimensional and consists of one diphosphorus tetraiodide molecule. P(1) is bonded in a 3-coordinate geometry to one P(1), one I(1), and one I(2) atom. There are two inequivalent I sites. In the first I site, I(1) is bonded in a single-bond geometry to one P(1) atom. In the second I site, I(2) is bonded in a single-bond geometry to one P(1) atom. is represented by the CIF file [CIF]
