![عکس صفحه اول مقاله: Synthesis and characterization of new nitrate-bridged polymeric complexes of mercury(II) with phosphorus ylides Synthesis and characterization of new nitrate-bridged polymeric complexes of mercury(II) with phosphorus ylides](/preview/png/1328134.png)
Reaction of phosphorus ylides of the type X–C6H4–COCHPAr3 (X = Cl and NO2; Ar = phenyl and p-tolyl) with Hg(NO3)2 · H2O in equimolar ratios using methanol as solvent are reported. X-ray crystal structure analysis of [Hg(ClC6H4C(O)CHPPh3)(NO3)(μ-NO3)]n · (DMSO)n shows that the 1:1 complex adopts the noncentrosymmetric polymeric structure in the solid state with NO-3 anion bridges. Variation of temperature or concentration in a 31P NMR study indicates that the disappearance of satellites, due to coupling to 199Hg, occurs at increasing temperature or decreasing concentration.
