Abstract
The syntheses of [(CH3)3Te]X {X = N3 (1), OCN (2), SCN (3), SeCN (4), [Ag(CN)2] (5)} and [(C6H5)3Te]X {X = N3 (6), SeCN (7), [Ag(CN)2] (8)}, their NMR spectroscopic data, vibrational spectra and single crystal structures are described. Compounds 1−4 are the first trimethyltelluronium pseudohalides, while the known compounds 6 and 7 have been prepared for completion of their analytical and structural properties. The occurrence of intermolecular Te···N, Te···O, Te···S and Te···Se contacts is thoroughly studied. The dicyanoargentates 5 and 8 were obtained in an attempt to prepare telluronium cyanides. Low-temperature 13C NMR spectroscopy of the [Ag(CN)2]− ion in solution has been carried out, with determination of the 13C−107/109Ag coupling. (© Wiley-VCH Verlag GmbH, 69451 Weinheim, Germany, 2002)
