P(NH2)4I is Tetraauricupride structured and crystallizes in the orthorhombic Cmme space group. The structure is zero-dimensional and consists of four hydriodic acid molecules and four tetraaminophosphonium molecules.
P(NH2)4I is Tetraauricupride structured and crystallizes in the tetragonal P4/nbm space group. The structure is zero-dimensional and consists of two hydriodic acid molecules and two P(NH2)4 clusters. In each P(NH2)4 cluster, P5+ is bonded in a 4-coordinate geometry to four equivalent N3- atoms. All P–N bond lengths are 2.33 Å. N3- is bonded in a distorted water-like geometry to one P5+ and two equivalent H1+ atoms. Both N–H bond lengths are 1.03 Å. H1+ is bonded in a single-bond geometry to one N3- atom.
