Abstract:- The condensation of amino group of aniline or substituted aniline with carbonyl group of salicylaldehyde or 4-dimethylaminobenzaldehyde in the presence of phenolic or benzylic hydroxyl groups can be prepared. The complexes containing such Schiff bases can be synthesised by direct mixing of the Schiff base with metal ions in appropriate organic solvents using microwave and reflux techniques. Metal ions such as, Zn(II) and Cd(II) ions can be introduced to get the corresponding metal complexes. The elucidation and the study of the resulted compounds performed, with different physiochemical tools, such as, elemental analyses, infrared and electronic spectroscopies. Conductivity, as well as magnetic moments. The CHN elemental analyses defined the fact that the formation of the Schiff bases and their complexes are in 1:1 [ M:L] ratio. The infrared spectral data of the obtained Schiff bases and their complexes displayed the proper coordination sites between the metal ions and the Schiff bases. The electronic spectral results confirmed the structure of synthesized complexes to be octahedral geometry with respect to each metal ion. The molar conductivity measurements revealed the property of the complexes to be non-electrolyte in nature.
