Mixed dithiolato alkylene dithiophosphate derivatives of arsenic(III) and antimony(III)

Mixed dithiolato alkylene dithiophosphate derivatives of arsenic(III) and antimony(III) with the general formula [GRAPHICS] (where, G = -CH2C(CH3)(2)CH2-; -CH2C(C2H5)(2)CH2-) have been synthesized for the first time by the replacement reactions of ethane-1,2-dithiolatoarsenic(III) chloride, ethane-1,2-dithiolatoantimony(III) chloride, toluene-3,4-dithiolatoantimony(III) chloride, respectively with sodium alkylenedithiophosphates in equimolar ratios in benzene. These new compounds are soluble in common organic solvents like benzene, chloroform and carbon tetrachloride. These have been characterised by elemental analysis, melting points as well as spectroscopic (IR and H-1. C-13 and P-31 NMR) studies and probable structures have been proposed.
