Synthesis, characterization and biological activity of mixed legend complexes of Ti (IV) with N, O, & S-donor legends

Abstract

A novel mixed legend complexes of the type[Ti(C₁₅H₁₂N₂O.X)₂(C₂H₅OCS₂)Cl] were synthesized by the reaction of titanium tetrachloride with[3-(2’-hydroxyphenyl)-5-(4’-X-substituted phenyl)-pyrazoline] and xanthate in 1:2:1 molar ratio in dry benzene and methanol under an inert atmosphere due to  the hygroscopic nature of TiCl₄. The newly prepared [Ti(C₁₅H₁₂N₂O.X)₂Cl₂] and [(C₁₅H₁₂N₂O.X)₂Ti(C₂H₅OCS₂)Cl] complexes were characterized by physico-chemical and various spectroscopic techniques like FT-IR, ¹H NMR, ¹³C NMR and elemental analysis. The distorted octahedral geometry with coordination number six, around the central metal ion (Titanium) in complexes can be proposed by the above spectral studies. The antimicrobial behavior of these newly synthesized titanium complexes was also studied.
