“…Weak interaction between Hg and aromatic rings in organomercury compounds was first demonstrated by conformational analysis using IH NMR spectroscopy for 3-arylpropylmercurials and confirmed by a crystal structure of one of these, [C1HgCH2C(Me)(OMe)CH 2 (p-OMePh)], which has the Hg atom 3.05 A above one of the phenyl bonds (Kiefer, Waters & Carlson, 1968). The ~H resonances of MeHg I1 in [MeHglC, CH2Ph] (Rabenstein, Ozubko, Libich, Evans, Fairhurst & Suvanprakorn, 1974) suggesting that the methyl group is shielded by the presence of a nearby aromatic ring.…”
