| Abstract: | Ligand Stabilized Cyclic and Polycyclic Aluminium Phosphorus and Aluminium Arsenic Compounds The reaction of AlCl3 with Li2AsSiRMe2 (R = CMe2iPr) in a mixture of ether and heptane yields the ether stabilized polycyclic compound (AlCl)4(AsSiRMe2)4(Et2O)2] ( 4 ) with a ladder shaped Al4As4 core structure. The shape of 4 is mostly similar to the aluminium phosphorus compound (AlCl)4(PSiiPr3)4(Et2O)2] ( 1 ) described recently 1]. These two compounds 1 and 4 can be cleaved into the cyclic compounds {AlCl(C5H5N)}2(PSiiPr3)2] ( 3 ) and {AlCl(NEt3)}2(AsSiRMe2)2] ( 5 ) by reaction with pyridine and NEt3, respectively. The compounds 3 , 4 , and 5 have been characterized by single crystal X‐ray diffraction. |
