| Abstract: | The reactions of triorganotin (IV) chloride with ferrocenyl aroylhydrazone derived from condensation of acetylferrocene and aromatic acidhydrazide yield heterobimetallic penta- and hexa-coordinated organotin(IV) complexes of the type R₃Sn(L) and R₃Sn(HL)Cl (where R=Me, Et or Ph HL=ferrocenyl aroylhydrazone). The ligands behave as bidentate, coordinating through carbonyl oxygen and azomethine nitrogen in keto and enolisation of keto form at low temperature and at room temperature respectively. The isolated complexes have been characterized by elemental analysis, molar conductance, infrared and NMR (¹H, ¹³C and ¹¹⁹Sn) spectral data. The ligands and their organotin complexes have been evaluated for antifungal activity against Alternaria alternata, Fusarium oxysporum and Rhizoctonia solani, as well as antibacterial activity against gram negative, (Escherichia coli) and gram positive bacilli (Bacilli subtilis) at 28ºC. The activity of the ligands is enhanced on complexation with triorganotin (IV) chloride. |
