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.

O, O’-Dialkyl and alkylene dithiophosphatogold (III)dichloride complexes of the type [(RO)2PS2]AuCl2 and [S2POGO]AuCl2, where R = Et, nPr, iPr, iBu, Ph, cyclohexyl and cyclopentyl, where G = CMe2CMe2-, have been synthesized in 80-90% yields by reaction of the corresponding acid or sodium salts of the appropriate dithiophosphoric acids in 1:1 ratio with gold (III) chloride in dry dichloromethane at room temperature. The compounds have been characterized by elemental analyses, IR and (1H, l3C, and 31P) NMR. The crystal structure of [S2POCMe2CMe2O]AuCl2, was determined. These new complexes have shown their growth inhibiting potential against various bacterial strains with moderate to good activity.
Dialkyl (alkylene) dithiophosphate adducts of anhydrous stannous chloride: Synthesis, characterization, and biological activities

Dialkyl (alkylene) dithiophosphate adducts of stannous chloride were synthesized by the reaction of anhydrous tin(II) chloride (SnCl2) and dialkyl (alkylene) dithiophosphoric acid in a 1:1 molar ratio, under anhydrous reaction conditions, below 5 °C in a closed vessel. The newly synthesized adducts were characterized by physicochemical and spectroscopic techniques [FT-IR, NMR (1H, 31P, and 119Sn), and mass spectrometry]. Coordination modalities have indicated a donor-acceptor interaction between sulfur and tin(II) moieties, where tin(II) acts as a Lewis acid. The adducts were found to have significant antibacterial activity against Escherichia coli and Pseudomonas aeruginosa, and antifungal activity against Aspergillus niger and Candida albicans.

An efficient method for the synthesis of Ptychodiscus brevis toxin O,O- di n-propyl (E)-2-[1-methyl 2-oxopropylidene]phosphorohydrazidothiolate (E) oxime (TG-1) and its analogues has been developed using thermally stable and recyclable silica gel and Na2SO4 as a condensing agent and water scavenger, respectively. The compounds were evaluated against fish Rasbora daniconius by determining the LC50 and LC90 values. The results of biological evaluation showed that these compounds have high degree of toxicity.

Following the investigation of the reaction of N,N'-diphenylguanidine with diorganyldithiophosphoric acids, it was shown that the reaction leads to the formation of diorganyldithiophosphate salts of N,N'-diphenylguanidine with a protonated nitrogen atom.The dithiophosphate salts of N,N'-diphenylguanidine decompose on heating to the starting compounds.The action of heat causes the disproportionation of the dithiophosphoric acids into O,O,S-triorganyl dithiophosphate and O-monoorganyl dithiophosphate.
REDOX REACTIONS OF ANTIMONY(III) O,O-DISUBSTITUTED PHOSPHORODITHIOATES WITH FERRIC CHLORIDE

The reaction of antimony(III) tris-(O,O-diethylphosphorodithioate) with three equivalents of ferric chloride in ether solution has been found to give ferrous chloride, bis-(O,O-diethylthiophosphoryl) disulfide and dichloroantimony O,O-diethyl phosphorodithioate as the major products.However, a relatively low yield of bis-(O,O-diethylthiophosphoryl) trisulfide was also obtained.The structures of these products were established by independent syntheses.Several additional antimony(III) tris-(O,O-disubstituted phosphorodithioates) were prepared, and the major organic product obtained by reaction of each of these compounds with three equiva lents of ferric chloride was the corresponding bis-(O,O-disubstituted thiophosphoryl) disulfide.A mechanism for this reaction has been suggested, and evidence in support of the mechanism has been presented.The various antimony(III) tris-(O,O-dialkyl phosphorodithioates) are passivating agents in petroleum refining.The results reported in this and in our previous papers indicate that such compounds undergo a variety of reactions with components of crude petroleum prior to the ultimate pyrolysis reactions which occur in the fluid catalytic cracking process.
