Synthesis and Structures of Triorganochalcogenium (Te, Se, S) Dinitramides

The syntheses of the triorganochalcogenium dinitramide salts [Ph3Te][N(NO2)2] (1), [Me3Te][N(NO2)2] (2), [Ph3Se][N(NO2)2] (3), [Me3Se][N(NO2)2] (4), [Ph3S][N(NO2)2] (5), and [Me3S][N(NO2)2] (6), their characterization by multinuclear NMR spectroscopy, vibrational spectra, and single‐crystal structures are described. The syntheses of the compounds were achieved with the help of [Ag(py)2][N(NO2)2] and [Ag(NCCH3)][N(NO2)2] as dinitramide transfer reagents. Whereas in the crystal structure of 1 different coordination modes to dinitramide moieties are present, the crystal structure of 3 shows only a single intermolecular contact to the dinitramide moiety. (© Wiley‐VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2008) The reactions of triorganochalcogenium halides with a dinitramide transfer reagent result in the first triorganochalcogenium dinitramides, which were characterized by NMR spectroscopy and vibrational data. The crystal structures for the phenyl salts [Ph3Te][N(NO2)2] and [Ph3Se][N(NO2)2] are reported.
