Synthesis and comparative antibacteral activity of Zn(II) and Fe(II) transition metal complexes with N-N-S-S donor ligand Rai Durgesh Kumar1 Department of Chemistry, Sam Higginbottom Institute of Technology and Sciences, Allahabad, Uttar Pradesh, India 1Corresponding author
Online published on 31 January, 2014. Abstract A series of metal complexes of Fe(II) and Zn(II) having the general composition [M(L)X2] with benzil bis (thiosemicarbazone) has been prepared and characterized by element chemical analysis, magnetic susceptibility measurements, and spectral (FTIR) studies. The IR spectral data suggest the involvement of Sulphur and Azomethane nitrogen in coordination to the central metal ion. On the basis of spectral studies, complexes of Zn (II) and Fe (II) show octahedral geometry. The antibacterial properties of the ligand and its metal complexes were also examined and it was observed that the complexes are more potent bactericides than the free ligand, against the sensitive organisms Staphylococcus aureus, Bacillus macerans as Gram positive bacteria, Vibro cholerae Somonella typhi, as Gram negative bacteria. Ciprofloxin as standard drug. Top Keywords Benzil bis (Thiosemicarbazone), Fe (II) Zn (II), Antibacterial, FTIR. Top | |
