چکیده (انگلیسی):

Metal complexes of Cr(III), Co(II) and Cd(II) ions were synthesizedwith a ONS containing Schiff base ligand, 2-bis(2-oxoindolin-3-ylidene)hydrazinecarbothioamide which was derived from the condensation reaction of thiosemicarbazide and isatin. The ligand and complexes were isolated from the reaction in the solid form and characterized by IR, UV-Visible, Thermal analysis and some physical measurements. Spectroscopic evidence indicated that the Schiff base behaved as ONS coordinating hexadentate chelating agent. Magnetic susceptibility data coupled with electronic spectra suggested a distorted octahedral structure of the complexes. The overall reaction was monitored by TLC and UV-Visible spectral analysis. The Schiff base and their metal complexes have been shown moderate to strong microbial activity.
