Abstract :Titaniuminsert ignore into journalissuearticles values(II); complexes of composition TiCl2insert ignore into journalissuearticles values(L);2 [where L = 2,2`-bipyridine insert ignore into journalissuearticles values(bipy);, 4,4`-dimethyl-2,2`-bipyridine insert ignore into journalissuearticles values(bpMe);, 4,4`-dimethoxy-2,2`-bipyridine insert ignore into journalissuearticles values(bpoMe);, 6,6`-dimethyl-2,2`-bipyridine insert ignore into journalissuearticles values(dpMe);, adamantylamine insert ignore into journalissuearticles values(ada);] were prepared by reacting titanium tetrachloride and N-containing bulky ligands in predetermined molar ratios. The complexes synthesized were characterized by different spectroscopic techniques, viz. UV-visible, FTIR, 1H NMR, and mass spectrometry. The stoichiometry of the complexes was established by their elemental analysis insert ignore into journalissuearticles values(chlorine and titanium estimation);. The unit cell parameters calculated by using the powder XRD tool confirm the monoclinic unit system and P lattice type for all complexes. Antibacterial screening of the ligands as well as the complexes was carried out to check their biological potential. It was found that the complex with 4,4`-dimethyl-2,2`-bipyridine ligand was a more potent bactericide than complexes with other ligands.
