The compound [2,6-(Me2NCH2)2C6H3]Hg(OAc) (1) was prepared by direct mercuration of 1,3-(Me2NCH2)2C6H4 with Hg(OAc)2. Treatment of 1 with excess of LiCl resulted in isolation of the chloride [2,6-(Me2NCH2)2C6H3]HgCl (2) in a good yield. The IR spectroscopy confirms the presence of the acetate group in 1. Both compounds 1 and 2 were characterized by solution multinuclear (1H, 13C and 199Hg) NMR spectroscopy and mass spectrometry. Their crystal and molecular structures were established by single-crystal X-ray diffraction. Different intermolecular interactions, i.e. Hg···Hg, O···Hg and C‒H···π (Arcentroid), were found for both compounds in solid state resulting in dimer or chain polymer associations.
