Abstract:

Two diorganotin(IV) complexes of general formula R2Sn[2-OC6H4CH=NDN=C(O)Ph] (R = Ph, 1; R = Me, 2) have been synthesized from the corresponding diorganotin(IV) dichloride and the Schiff base derived from salicylaldehyde and benzoyl hydrazide. The two compounds have been characterized by elemental analysis, IR and NMR (1H, 13C, 15N, 119Sn) spectra, and their structures have been confirmed by single crystal X-ray structure analysis.

Abstract:

A series of new hetero binuclear complexes of copper(II) and lead(II) using Schiff base have been synthesized. The Schiff base has been derived from the condensation reaction between Salicylaldehyde and 1,2-Ethylenediamine. The hetero binuclear complexes have been characterized by using elemental analysis, molar conductance measurement, magnetic susceptibility studies, UV-Vis and IR spectra. The studies revealed square planar geometry for the complexes with coordination number four.

Abstract:

Novel Schiff bases and their metal complexes were derived from some hetero cyclicβ-diketones with 4-phenyl-2-aminothiazole. All the synthesized compounds were confirmed their structure by Elemental analysis, FT-IR,1H NMR,13C NMR, Mass spectra, TGA analysis and UV spectra. All the compounds were tested for their antibacterial activity. Spectroscopic measurements suggest that all Schiff base metal complexes are of type ML2.(H2O)2(M=Mn, Fe, Co, Ni and Cu) and all the metal complexes shows moderate antibacterial activity in the agar cup assay method.
