The Schiff bases, formed by condensation of 2-thiophenecarboxaldehyde with 2-aminothiophenol (LH) and propane-1,2-diamine (L1), and their complexes of Ni(II), Cu(II), Zn(II) and Cd(II) have been prepared and characterized by elemental analysis, and magnetic and spectroscopic measurements. Infrared and NMR spectra of the complexes agree with the coordination to the central metal atom through the nitrogen of the azomethine (-HC=N-) group and the sulfur atom of the thiophene ring. Magnetic susceptibility data coupled with electronic suggest octahedral structure for the complexes. Conductance measurements suggest the non-electrolytic nature of the complexes. Stoichiometry of complexes has been suggested as [M(L)2] and [ML1Cl2]. The Schiff base and its metal chelates have been screened for their in vitro antibacterial activity against four human pathogenic bacteria. Ligands show moderately whereas some of metal chelates show highly antibacterial activity against them.
