Synthesis and Characterization of Copper(Ii) and Nickel(Ii) Complexes of the Schiff Bases Derived From ?3-tetrahydrobenzaldehyde and 2-methyl-?3-tetrahydrobenzaldehyde and Glycine

Copper(II) and nickel(II) complexes with the Schiff bases derived from ?3-tetrahydrobenzaldehyde or 2-methyl-?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 1H 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.
