Abstract:

New tin (IV) complexes of empirical formula, [Cl2 Me2 Sn(H2 L)1-3], where ((H2 L)1-3: Methyl-2- {[1-methyl-2-(2-hydroxy-3-methoxyphenyl)methylidynenitrilo]ethyl}amino-1-cyclopentenedithiocarboxylate [H2cd3OMesalMeen], Methyl-2-{[1-methyl-2-(2-hydroxy-4-methoxyphenyl)methylidynenitrilo]ethyl}amino-1-cyclopentenedithiocar-boxylate, [H2 cd4OMesalMeen], Methyl-2-{[1-methyl-2-(2-hydroxy-5-methoxyphenyl)-methylidynenitrilo]ethyl}amino-1- cyclopentenedithiocarboxylate, H2 cd5OMesalMeen]) have been prepared and fully characterized by a variety of physico-chemical techniques. Spectroscopic data suggest that in three complexes the Schiff base ligand is coordinated through oxygen. The Schiff base ligands and their Sn (IV) complexes were tested against two pathogenic bacteria (Staphylococcus aureus as Gram-positive bacteria and Escherichia coli as Gram-negative bacteria). All the complexes exhibit higher antibacterial activity than the free ligands. Computation analyses at the level of DFT with Becke’s three parameter hybrid methods were performed to study the geometrics, electronic structures; HOMO- LUMO energy gap, dipole moment and its calculated vibrational frequencies were investigated. An excellent agreement between the experimental and calculated results obtained from the two spectra methods.

Bidentate Isatin Schiff Base Ligands Oxovanadium (IV) Complexes

The aim of the present study is to synthesize the oxovanadium complex of the V3+ ion with isatin sciff bases. Spectroscopic methods have been used to confirm these models of complexation and to understand the structures of the species formed in methanolic solution. We also have isolated a complex of Vanadium (III) with isatin schiff bases in the solid phase.
