AlPNCl5 is Indium-like structured and crystallizes in the triclinic P-1 space group. The structure is zero-dimensional and consists of one AlPNCl5 cluster. Al(1) is bonded to two equivalent N(1), one Cl(3), and one Cl(5) atom to form AlN2Cl2 tetrahedra that share corners with two equivalent P(1)NCl3 tetrahedra and  an edgeedge with one Al(1)N2Cl2 tetrahedra. P(1) is bonded to one N(1), one Cl(1), one Cl(2), and one Cl(4) atom to form PNCl3 tetrahedra that share corners with two equivalent Al(1)N2Cl2 tetrahedra. N(1) is bonded in a distorted T-shaped geometry to two equivalent Al(1) and one P(1) atom. There are five inequivalent Cl sites. In the first Cl site, Cl(1) is bonded in a single-bond geometry to one P(1) atom. In the second Cl site, Cl(2) is bonded in a single-bond geometry to one P(1) atom. In the third Cl site, Cl(3) is bonded in a single-bond geometry to one Al(1) atom. In the fourth Cl site, Cl(4) is bonded in a single-bond geometry to one P(1) atom. In the fifth Cl site, Cl(5) is bonded in a single-bond geometry to one Al(1) atom.
