MIXED BIS(DIALKYL DITHIOCARBAMATE) DIALKYL DITHIOPHOSPHATE COMPLEXES OF ANTIMONY(III)

Displacement reactions of chloroantimony(III) bis(dialkyl dithiocarbam ates) with sodium dialkyl dithiophosphates in stoichiometric ratios in anhydrous benzene yielded mixed bis(dialkyl dithiocarbamate) dialkyl dithiophosphates of antimony(III) of the type (XCS2)(2)SbS2P(OR)(2) (w here, X = N(CH3)(2), N(C2H5)(2), N(CH2)(4); R = n-Pr, i-Pr, n-Bu and i -Bu). These derivatives are yellow crystalline solids which are solubl e in common organic solvents like benzene, chloroform, carbon tetrachl oride etc. Spectroscopic studies (IR, H-1 and P-31 NMR) indicate the b identate behaviour of both the dithiocarbamate and dithiophosphate moi eties of these complexes.
