In situ Alkylation of 4,4′‐Vinylenedipyridine for Inorganic‐Organic Iodides/Iodidomercurates

Solvothermal reactions of HgI2, 4,4′‐vinylenedipyridine, and HI in alcoholic solution (methanol, ethanol, or pentanol) gave rise to a family of organic‐inorganic hybrid complexes, formulated as [C14H16N2][I4]2– (1), [C16H20N2][HgI4] (2), and [C22H32N2][HgI4]4 (3).

Description
Summary:Solvothermal reactions of HgI2, 4,4′‐vinylenedipyridine, and HI in alcoholic solution (methanol, ethanol, or pentanol) gave rise to a family of organic‐inorganic hybrid complexes, formulated as [C14H16N2][I4]2– (1), [C16H20N2][HgI4] (2), and [C22H32N2][HgI4]4 (3). Single‐crystal X‐ray diffraction reveals that all three compounds are discrete structures, including the inorganic anion [I4]2– or [HgI4]2– and an organic cation, where the resulting organic cations were generated in situ alkylation reactions of 4,4′‐vinylenedipyridine with alcohols, with cleavage of the alcoholic C–O bond followed by a one‐step in situ N‐alkylation reaction of 4,4′‐vinylenedipyridine in acidic HI solution. X‐ray powder diffraction (XRD), 1H NMR and 13C NMR, energy‐dispersive X‐ray (EDS), IR, as well as UV/Vis/NIR spectroscopy, elemental analysis, and thermogravimetric analysis (TGA) were used to characterize the complexes.
