(Hg3(HC(PPh2)3)(OAc)n)(O3SCF3)m, n+m=6: COMPLEXES CONTAINING AN ACIDIC CARBON
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.

METALLOMETHANE. VII. 199Hg-NMR-STUDIEN AN MERCURIMETHANEN CH4-n(HgX)n (X = Cl, Br, I UND CN)
199Hg NMR spectra of the partly newly prepared mercurimethanes CH4-n(HgX)n (1n4; X=Cl, Br, I and CN) have been measured.The chemical shifts δ(199Hg) indicate increasing deshielding of the mercury nuclei with increasing n and in the series I a fixed n are explained by changes in population and extension of the 6p orbitals of mercury.The variations of δ(199Hg) with n correlate with the course of excitation energies ΔE.The coupling constants 2J(199Hg-1H) decrease with growing trans influence of the ligands X.
