eng	Intramolecularly Coordinated Stannanechalcogenones: X-ray Structure of [2,6-(Me2NCH2)2C6H3](Ph)Sn=Te	The treatment of an intramolecularly coordinated organotin(IV) dichloride, [2,6-(Me2NCH2)2C6H3](Ph)SnCl2 (1), with Li2E (E = S, Se, Te) afforded thermally stable dimeric diarylstannanethione [{2,6-(Me2NCH2)2C6H3}(Ph)Sn(mu-S)]2 (2) and monomeric diarylstannaneselone and -tellurone [{2,6-(Me2NCH2)2C6H3}(Ph)Sn=E] (E = Se (3), Te (4)). Compounds 2?4 were characterized by means of elemental analyses and 1H, 13C, 77Se, 119Sn, and 125Te NMR spectroscopy. The molecular structures of 2 and 4 were determined by single-crystal X-ray diffraction analysis. Solution NMR studies revealed dependence of the structure of compounds 2 and 3 on the solvent (C6D6 or CDCl3). In addition, the synthesis of dimeric stannanetellurone [{2,6-(Me2NCH2)2C6H3}(Bu)Sn(mu-Te)]2 (5) showed an influence of the organic group R (R = Bu or Ph) on the structure of diorganotin(IV) tellurides 4 and 5.
