Reactions of phosphonium ylides (4-MeC6H4) 3PCHC(=O)(2-C4H3S) (tptpy), Ph 3PCHC(=O)(2-C4H3O) (fppy), and (4-MeC 6H4)3PCHC(=O)(4-BrC6H4) (bbtppy) with HgX2 (X=Cl, Br, and I) in equimolar ratios in MeOH as solvent leads to the binuclear products 1-3 (Scheme 1). The bridgesplitting reaction of the binuclear complex [{HgI2(bbtppy)}2] (3c) by DMSO yields the mononuclear complex [HgI2 · (bbtppy) (DMSO)] (3d) (Scheme 2). This bridge-splitting reaction can also be a method for the synthesis of mononuclear products. C-Coordination of the ylide and O-coordination of DMSO are demonstrated by a single-crystal X-ray-analysis of the mononuclear complex 3d. Characterization of the obtained compounds was also performed by means of elemental analysis and IR and 1H-, 31P-, and 13C-NMR spectroscopy. A theoretical study of some HgII complexes with phosphonium ylides is also reported.
