in water The silver salt of O,O-diethyl dithiophosphate was prepared from equimolar aq. solns. of AgNO3 and NH4(1+){S2P(OEt)2}(1-) and reacted in situ with an aq. soln. of Et3TeI. The react. mixt. was wartmed up to 70°C for ca. 3 h.; React. mixt. cooled to room temp., Et3TeAg4I5 extd. with CH2Cl2 and pptd. with CHCl3; elem.anal.; Et2Te and EtSP(S)(OEt)2 detected in the extn. residue by MS.;
