Reaction of two new phosphorus ylides Ph3PCHCOC10H7 (Y1) and Ph3PCHCOC4H3S (Y2) with mercury(II) halides and a previously reported ylide (p-tolyl)3PCHCOOCH2Ph (Y3) with CdCl2 in equimolar ratios using methanol as solvent yielded binuclear complexes of the type [(Y).HgX2]2 (Y=Y1 and Y2, X=Cl, Br and I) and a complex of [(Y3).HgCl2]2. The latter ylide reacts with Hg(NO3)2.H2O in the same solvent with equimolar ratios to give a polynuclear complex [Hg(Y3)(NO3)(μ-NO3)]n. Also, the reaction between ylides and AgNO3 in 1:2 molar ratios gave mononuclear complexes. Characterization of these products was carried out by elemental analysis, IR and multinuclear NMR techniques.
