A new route to synthesize nano-sized Ti(IV) mixed ligand complexes have been investigated by the reaction of titanium(IV) chloride with ammonium salts of dithiophosphate and 3(2'-hydroxyphenyl)-5-(4- substituted phenyl) pyrazolines. The resultant complex is then treated with H2S gas to get sulfur bridged dimer of Ti(IV) complex, a precursor of TiS2. The morphology of the complexes was studied by employing XRD which shows that all the complexes are amorphous solid. Molecular weight measurements, elemental analysis in conjugation with spectroscopic (IR, 1H NMR, 13C NMR and 31P NMR) studies revealed the dimeric nature of the complexes in which pyrazoline and dithiophosphate are bidentate. Scanning electron microscopic image and XRD indicate that the particles are in the nano range (50 nm). Putting all the facts together, coordination number six is proposed for titanium with octahedral geometry.

Pyridoxonium salts of chiral linear and cyclic dithiophosphoric acids were obtained by the reactions of pyridoxine with bis{2-О-[2-methyl-(2S)-3-O-propionyl]}, bis{2-О-[1,4-О,О-dimethyl-(2S)-succinyl]}, and O,O-di-2-butyl dithiophosphoric acids, and cyclic dithiophosphoric acids of 1,3,2-dioxaphosphorinane, 1,3,2-dioxaphospholane, and 1,3,2-dioxaphosphepin structure. Syntheses of acetonide pyridoxonium О,О-dimenthyl dithiophosphates were carried out by the reaction of seven-membered pyridoxine acetonide with О,О-dimenthyl dithiophosphoric acids obtained from (–)-(1 R,2S,5R)-menthol and (+)-(1S,2R,5S)-menthol. Diacetonide pyridoxonium bisdithiophosphonate was also prepared. The antibacterial and antifungal activities of pyridoxonium chiral linear and cyclic dithiophosphates were evaluated.

2-Mercapto-2-thiono-1,3,2-dioxaphospholanes and dioxaphosphorinanes, have been synthesized by the reactions of phosphorus pentasulfide with some 1,2-diols (viz., butane-2,3-diol and 2,3-dimethylbutane-2,3-diol) and 1,3-diols (viz., 2-methylpentane-2,4-diol, 2,2-dimethylpropane-1.3-diol and 2,2-diethylpropane-1,3-diol) in 1:2 molar ratio in dry benzene.These volatile compounds have been purified by distillation under reduced pressure.The 2-methylpentane-2,4-diol derivative, however, decomposed during attempted distillations.These new compounds have been characterized by elemental analysis, molecular weight determinations, measurement of pKa values and IR as well as NMR spectroscopic studies.The ammonium and sodium salts of some of these acids have also been characterized.
