PN9S is Indium-like structured and crystallizes in the monoclinic P2_1/c space group. The structure is zero-dimensional and consists of four PN9S clusters. P(1) is bonded in a distorted tetrahedral geometry to one N(1), one N(4), one N(7), and one S(1) atom. There are nine inequivalent N sites. In the first N site, N(7) is bonded in a bent 120 degrees geometry to one P(1) and one N(8) atom. In the second N site, N(8) is bonded in a linear geometry to one N(7) and one N(9) atom. In the third N site, N(1) is bonded in a bent 120 degrees geometry to one P(1) and one N(2) atom. In the fourth N site, N(9) is bonded in a single-bond geometry to one N(8) atom. In the fifth N site, N(2) is bonded in a linear geometry to one N(1) and one N(3) atom. In the sixth N site, N(3) is bonded in a single-bond geometry to one N(2) atom. In the seventh N site, N(4) is bonded in a distorted bent 120 degrees geometry to one P(1) and one N(5) atom. In the eighth N site, N(5) is bonded in a linear geometry to one N(4) and one N(6) atom. In the ninth N site, N(6) is bonded in a single-bond geometry to one N(5) atom. S(1) is bonded in a single-bond geometry to one P(1) atom.
