Abstract: | The complexes Na(Et2O)(dpp-BIAN)AlEt2 (5) and Na(η6-C6H6)(dpp-BIAN)AlEt2 (6) were synthesized by reactions of the disodium salts of dpp-BIAN (dpp-BIAN is 1,2-bis(2,6-di-isopropylphenyl)imino]acenaphthene)
with 1 equiv. of Et2AlCl in diethyl ether and benzene, respectively. The structures of both complexes were established by X-ray diffraction. In
molecules 5 and 6, diethylaluminum is chelated by the dianionic dpp-BIAN ligand. The sodium cations in molecules 5 and 6 are located above the plane of the diimine fragments and coordinate the Et2O or benzene molecule, respectively.
Dedicated to Academician G. A. Abakumov on the occasion of his 70th birthday.
