Crystal structure of AlPCl8

The crystal structure of aluminium phosphorus chloride (systematic name: phosphorus tetrachloride tetrachloridoaluminate), (PCl 4 )[AlCl 4 ] or AlPCl 8 , was determined and refined using single-crystal X-ray diffraction data. The compound crystallizes in the orthorhombic space group Pbcm . The asymmetric unit comprises one Al atom, one P atom, and five Cl atoms. The structure is characterized by isolated AlCl 4 and PCl 4 tetrahedra, isostructural with FePCl 8 and GaPCl 8 .
