Synthesis and Characterization of Binuclear Indium(III) Complexes with Bis-schiff Bases Derived from Benzidine or Its Derivatives

摘要

By reactions of indium chloride tetrahydrate with three bis-Schiff bases ligands (N, N'-bis (3-methoxy-salicylidene)benzidine = L~1; N, N'-bis (3-methoxysalicylidene)-2, 2'-dimethylbenzidine =L~2; N, N'-bis (3-methoxysalicylidene)-o-dianisidine = L~3), respectively, three novel corresponding complexes l～3 were obtained. The complexes were characterized by infrared spectrum, molar conductance, elemental analysis and thermal gravimetric analysis. The chemical formulae of the complexes l～3 were determined as (InCl_3)_2L~n (1, n = 1; 2, n = 2; 3, n = 3). All the complexes are constructed with binuclear indium ions. Every complex consists of two central In (III) ions, one corresponding bis-Schiff base ligand and six Cl~-.
