AlPH9(CCl)3 is Silicon tetrafluoride-derived structured and crystallizes in the monoclinic P2_1/m space group. The structure is zero-dimensional and consists of two AlPH9(CCl)3 clusters. Al(1) is bonded to one P(1), one Cl(2), and two equivalent Cl(1) atoms to form AlPCl3 tetrahedra that share  a cornercorner with one C(2)PH3 tetrahedra and corners with two equivalent C(1)PH3 tetrahedra. There are two inequivalent C sites. In the first C site, C(1) is bonded to one P(1), one H(1), one H(2), and one H(3) atom to form distorted CPH3 tetrahedra that share  a cornercorner with one Al(1)PCl3 tetrahedra,  a cornercorner with one C(1)PH3 tetrahedra, and  a cornercorner with one C(2)PH3 tetrahedra. In the second C site, C(2) is bonded to one P(1), one H(4), and two equivalent H(5) atoms to form distorted CPH3 tetrahedra that share  a cornercorner with one Al(1)PCl3 tetrahedra and corners with two equivalent C(1)PH3 tetrahedra. P(1) is bonded in a tetrahedral geometry to one Al(1), one C(2), and two equivalent C(1) atoms. There are five inequivalent H sites. In the first H site, H(1) is bonded in a single-bond geometry to one C(1) atom. In the second H site, H(2) is bonded in a single-bond geometry to one C(1) atom. In the third H site, H(3) is bonded in a single-bond geometry to one C(1) atom. In the fourth H site, H(4) is bonded in a single-bond geometry to one C(2) atom. In the fifth H site, H(5) is bonded in a single-bond geometry to one C(2) atom. There are two inequivalent Cl sites. In the first Cl site, Cl(2) is bonded in a single-bond geometry to one Al(1) atom. In the second Cl site, Cl(1) is bonded in a single-bond geometry to one Al(1) atom.
