Abstract: Thiosemicarbazones, were obtained by condensation of thiosemicarbazide with suitablealdehydes or ketones, act as ligand in the preparation of their complexes. They bind to themetal through N and S atoms. Their metal complexes may have biological properties. In thiswork, di chloro 4-pyridinecarboxaldehyde thiosemicarbazone cadmium (II) was synthesizedby an efficient and facile microwave heating technique. The reaction was performed usingCdCl2.H2O as metal source and 4-pyridinecarboxaldehyde thiosemicarbazone as ligand in 1:1molar ratio in EtOH under microwave irradiation with the power of 100 W for 30 sec. Theprogress of the reaction was monitored by TLC. The product was characterized by Fouriertransform infrared (FT-IR), 1H-, 13C- NMR spectroscopy and elemental analysis.
