Synthesis And Characterization Of O-Alkyl Or O-Aryl Trithiophosphate Derivatives Of Chromium (Iii)

Complex of the type Cr[R-O-P(S)S2]3 where (R= Me, Et, Pri , Bui , ph.) have been synthesized by the reactions of chromium trioxde (CrO3) and O-alkyl / O-aryl trithiophosphoric acid in 1:3 molar ratio in anhydrous benzene. O-alkyl / O-aryl trithiophosphate derivatives of chromium are light brown coloured monomeric solid which are soluble in common organic solvents. These complex have been characterized by elemental analysis, (C,H,S) molecular weight measurement, IR and NMR (1 H, 12C, 31P) spectral studies. On the basis of above studies octahedral geometry of O-alkyl/O-aryl trithiophosphate derivatives of chromium has been suggested, which are consists with six coordinated chromium and bidentate behaviour of the trithiophosphate moiety
