Hg-Donor Ligands

SnMe Cl3 provides [PtPh(PPh3)2(SnMe h2- )Cl]. An approximate thermochemical analysis suggests that M—C insertion may be favoured relative to M—Cl insertion for M = Sn, Ge, or Si, with the reactivity decreasing in this order. 

Stable CT-bonded Pt—Hg complexes may be prepared when perfluorinated groups or sterically large groups near to the bimetallic bond are present [equation (25) X = halogen or Hg is eliminated on treatment with CF3CO2H yielding
