A dimeric alkyl complex supported by an O,S,S,O-tetradentate diphenolate ligand

The title dinuclear compound, bis[μ-6,6'-di-tert-butyl-4,4′-dimethyl-2,2-(ethylenedithio)diphenolato]bis[methylaluminium(I)], [Al2(CH3)2(C24H32O2S2)] or [AlMe(etbmp)]2 [where etbmpH2 is 6,6′-di-tert-butyl-4,4′-dimethyl-2,2- (ethylenedithio)diphenol], was obtained by reaction of trimethylaluminum with etbmpH2, as shown by X-ray diffraction of a single crystal. The molecule possesses a crystallographic twofold axis.
