Synthesis and spectral behavior of nanometric Ti(IV) complexes with nitrogen,sulfur, and oxygen donors

To study the spectral behavior of Ti(IV) complexes with sulfur donors, several new nano-sized mixed ligand complexes of Ti(IV) have been synthesized by the reaction of titanium(IV) salts with 3(2′-hydroxyl phenyl)-5-(4-substituted phenyl)pyrazolines and ammonium salts of dithiophosphates. Spectroscopic and X-ray diffraction studies reveal amorphous and monomeric complexes. The Ti(IV) complexes show octahedral geometry in which dithiophosphate and pyrazoline are bidentate. Transmission electron microscopic image shows that the particle size ranges from 50 to 90?nm.
