摘要

Eight new dimethylgallium complexes bearing 4-alkyl-2.6-bis(aryliminomethlene))-phenol ligands of type Me2GaL (L = 4-methyl-2, 6-bis-(phenyliminomethylene)-phenolato (3); L = 4-methyl-2,6-bis-(p-methylphenyliminomethylene)-phejiolato (4); L = 4-methyl-2,6-bis-(1-naphthyliminomethylene)- phenolato (5); L = 4-methyl-2,6-bis-(2-chlorophenyliminomethylene)-phenolato (6); 4-tert-butyl-2,6-bis(phenyliminomethylene)-phenolato (7); L = 4-tert-butyl-2.6-bis-)-methylphenyliminomethylene)-phenolato (8); L = 4-tert-butyl-2,6bis-(1-naphthyliminomethylene)-phenolato (9); and L = 4-tert-butyl-2,6-bis-(2-chlorophenyliminomethylene)-phenolato](3) have been synthesized by the reaction of trimethylgallium with appropriate phenol. The complexes obtained have been characterized by elemental analysis, 'H NMR, IR and mass spectroscopy, respectively. The solid-state structures of dimethyl[4-methyl-2,6-bis-(p-methylphenyliminomethylene)-phenolato]gallium (4) have been determined by X-ray single crystal analysis. In the structure, Ga atom is coordinated by one nitrogen atom and the other nitrogen atom remains constant. The distorted tetrahedron geometry around gallium is presented. (c) 2006 Elsevier B.V.
