Materials Data on PI2 by Materials Project
PI2 crystallizes in the triclinic P-1 space group. The structure is zero-dimensional and consists of one diphosphorus tetraiodide molecule. P is bonded in a 3-coordinate geometry to one P and two equivalent I atoms. The P–P bond length is 2.25 Å. Both P–I bond lengths are 2.49 Å. I is bonded in a single-bond geometry to one P atom.
