Article abstract of DOI:10.1016/0022-328X(86)80030-4

The reaction of the ligand HC(PPh2)3 (tripod) with Hg(OAc)2 and (Hg(Me2SO)6)(O3SCF3)2 in various stoichiometries but with a tripod/Hg ratio of 1/3 gives complexes which are carbon acids.The acidity of the methine group is attributed to the cumulative electron-withdrawing effect of the (PPh2Hg(II)) groups.The new complexes were characterized by 31P and 199Hg NMR spectroscopy.The 199 Hg, 199Hg couplings have values between 1050 and 1710 Hz.
