Synthesis and characterization of N-(2-thienylmethylidene)-1- propanamine and its metal complexes


Rhodium(I), palladium(II), zinc(II) and cadmium (II) complexes of type ML2Cl2, where M is Rh(I), Pd(II), Zn(II) and Cd(II) and L is Schiff base N-(2-thienylmethylidene)-1-propanamine (TNAP), formed by condensation of 2-thiophenecarboxaldehyde (2-TFCA) and propylamine (PA) have been synthesized. The Schiff base ligand and metal complexes were characterized by elemental analysis, magnetic and spectroscopic measurement. Formula determination by continuous variation method suggested the stoichiometry of 1:2 (metal: ligand). Infrared and NMR spectra of the complexes suggested coordination to the metal atom through the nitrogen and sulphur atoms. Conductance measurement suggested the non-electrolytic nature of the complexes
