Optical Properties and Structure of N-Salicylidene-d (+)-α-methylbenzylamine Nickel (II) Chelate

Abstract

The electronic absorption and circular dichroism (CD) spectra of Ni (II) complex derived from N-salicylidene-d (+)-α-methylbenzylamine (I) were measured in various solvents. The chloroform solution of Ni (II) complex show the electronic absorption and CD spectra which are different from those in methanol and pyridine solutions. The Ni (II) complex took an octahedral structure in methanol or pyridine, and square planar structure in chloroform. Proton magnetic resonance spectra of Al (III) complexes of (I) and various N-salicylideneimines were measured and the relationship between chemical shift of imine proton and the structure of amine was discussed.
