Titanium(IV) Complexes of Unsymmetrical Schiff Bases Derived from Ethylenediamine and o-Hydroxyaldehyde/Ketone and Their Anti-microbial Evaluation

The titanium(IV) complexes of the unsymmetrical Schiff base ligands (L) of ethylenediamine and salicylaldehyde, o-hydroxyacetophenone, o-hydroxynapthaldehyde have been prepared and characterized when unsymmetrical ligands are synthesized through in situ partial displacement of the symmetrical bis-Schiff bases. Compounds have been characterized by elemental analysis, electronic, (Infra-red) IR, H-1 NMR spectral data, magnetic susceptibility measurement and molar conductance and eight coordinated geometry of the complexes was proposed. The complexes have been found to posses 1:2:1 (M:L:B) stoichiometry (B is the secondary ligand). The bio-efficacy of the prepared complexes has been examined against the growth of bacteria and fungi in vitro to evaluate their anti-microbial potential.
