The Synthesis and characterization of five-coordinate Schiff base complexes of gallium

Abstract

This work is an exploration into the synthesis and characterization of five-coordination of gallium complexes of ligands. (E)-2-(2-hydroxybenzylideneamino)phenol (1), (E)-2-((phenylim,no)methyl)phenol (2), 2-2'-(1E,1E')-(1,4-phenylenebis(azan-1-yl-ylidene))bis(methan-1-yl-1-ylidene)diphenol (3), 8-hydroxyquinoline (4). Fully characterized examples include those of general formula LGL', where L:1, L'2,3 or 4. Ligands and complexes were characterized by means of elemental analysis, infrared spectroscopy,1H NMR, thermal analyses, and magnetic susceptibility measurements.
