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

Mixed dithiolato alkylene dithiophosphate derivatives of arsenic(III) and a ntimony(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 et hane-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 a nd carbon tetrachloride. These have been characterised by elemental analysi s, melting points as well as spectroscopic (IR and H-1. C-13 and P-31 NMR) studies and probable structures have been proposed.
