Synthesis and Characterization of Copper(II) and Nickel(II) Complexes of the Schiff Bases Derived From Delta(3)-Tetrahydrobenzaldehyde and 2-Methyl-Delta(3)-Tetrahydrobenzaldehyde and Glycine

Copper(II) and nickel(II) complexes with the Schiff bases derived from Delta(3)-tetrahydrobenzaldehyde or 2-methyl-Delta(3)-tetrahydrobenzaldehyde and glycine were synthesized. These compounds have been characterized by elemental analyses, conductivity measurements and infrared spectroscopy. The Schiff base ligands and their complexes have been further characterized by H-1 NMR The results suggest that the Schiff base acts as a bidentate ligand which bonds to the metal ions through the imino nitrogen and carboxylate oxygen. The potassium salts of the Schiff bases are 1:1 electrolytes, but all the complexes are non-electrolytes.
