Microwave-assisted synthesis, spectroscopy and antimicrobial studies of mono(cyclopentadienyl)titanium(IV) derivatives of bis(Schiff bases) derived from 1, 1' -diacetylferrocene and 3-substituted phenyl-4-amino-5-mercapto-1 ,2,4-triazoles

The reactions of mono(cyclopentadienyl)titanium(IV) trichloride with a new class of Schiff bases (H₂L), derived by condensing 1,1' -diacetylferrocene with different 3-substituted phenyl-4-amino-5-mercapto-1,2,4-triazoles, have been studied both by a conventional stirring method and also using microwave technology. Binuclear products of type [{η⁵-C₅H₅)TiCl₂}₂ (L)] have been isolated in both cases. Tentative structural conclusions are drawn for the reaction products based upon analysis, electrical conductance, magnetic moment and spectral (UV-Visible, IR, ¹H NMR and ¹³C NMR) data. FAB mass spectra of complexes were also recorded to confirm the binuclear structures. Studies were conducted to assess the growth inhibiting potential of the ligands and complexes against various fungal and bacterial strains.
