Aluminum Dihalide Complexes Based on the 1,2-bis[(2,6-dibenzhydryl-4-methylphenyl)imino]Acenaphthene Ligand

Abstract

Reduction of Ar^BIG-bian (Ar^BIG-bian = 1,2-bis[(2,6-dibenzhydryl-4-methylphenyl)imino]acenaphthene) by an excess of metal aluminum in the presence of AlCl₃, AlBr₃ or AlI₃ in toluene leads to the formation of dihalide anion-radical complexes [(Ar^BIG-bian)^–AlX₂] (X = Cl (1), Br (2), I (3)). The newly obtained compounds 1, 2, 3 are isolated in the crystal state and characterized by IR and EPR spectroscopies and by elemental analysis. Molecular structures of the complexes are determined by XRD.
