PNCl2 is Indium-like structured and crystallizes in the orthorhombic Pnma space group. The structure is zero-dimensional and consists of four 2,2,4,4,6,6-hexachloro-1,3,5,2,4,6-triazatriphosphinane-2,4,6-triium molecules. There are two inequivalent P sites. In the first P site, P(1) is bonded to one N(1), one N(2), one Cl(3), and one Cl(4) atom to form corner-sharing PN2Cl2 tetrahedra. In the second P site, P(2) is bonded to two equivalent N(1) and two equivalent Cl(1,2) atoms to form corner-sharing PN2Cl2 tetrahedra. There are two inequivalent N sites. In the first N site, N(1) is bonded in a bent 120 degrees geometry to one P(1) and one P(2) atom. In the second N site, N(2) is bonded in a bent 120 degrees geometry to two equivalent P(1) atoms. There are three inequivalent Cl sites. In the first Cl site, Cl(3) is bonded in a single-bond geometry to one P(1) atom. In the second Cl site, Cl(4) is bonded in a single-bond geometry to one P(1) atom. In the third Cl site, Cl(1,2) is bonded in a single-bond geometry to one P(2) atom.

In the first P site, P(1) is bonded to one N(1), one N(2), one Cl(3), and one Cl(4) atom to form corner-sharing PN2Cl2 tetrahedra. The P(1)-N(1) bond length is 1.59 Å. The P(1)-N(2) bond length is 1.60 Å. The P(1)-Cl(3) bond length is 2.02 Å. The P(1)-Cl(4) bond length is 2.01 Å. In the second P site, P(2) is bonded to two equivalent N(1) and two equivalent Cl(1,2) atoms to form corner-sharing PN2Cl2 tetrahedra. Both P(2)-N(1) bond lengths are 1.59 Å. There is one shorter (2.01 Å) and one longer (2.02 Å) P(2)-Cl(1,2) bond length. There are two inequivalent N sites. In the first N site, N(1) is bonded in a bent 120 degrees geometry to one P(1) and one P(2) atom. In the second N site, N(2) is bonded in a bent 120 degrees geometry to two equivalent P(1) atoms.
