AlPH8(CCl)3 is alpha U structured and crystallizes in the monoclinic P2_1 space group. The structure is zero-dimensional and consists of two AlPH8(CCl)3 clusters. Al(1) is bonded to one P(1), one Cl(1), one Cl(2), and one Cl(3) atom to form AlPCl3 tetrahedra that share  a cornercorner with one C(1)PH3 tetrahedra and  a cornercorner with one C(2)PH3 tetrahedra.
