Abstract: Some bivalent metal ion complexes of Schiff bases derived from formylformic acid and thiosemicarbazide were synthesized.The composition of the complexes were determined as M(HFFTSC)2·nH2O(M=Co(Ⅱ),Ni(Ⅱ),n=2;M=Zn(Ⅱ),n=1;M=Mn(⒓),Pb(1),n=0) and Cu(FFTSC)·H2O based on the elemental analysis data and molar conductance measurements.The IR results showed that the ligand behaves as in a tridentate manner.The antibacterial activity of the complexes were examined.

Key words: formylformic acid thiosemicarbazide Schiff base, transition element, complex, antibacterial activity
