Intramolecularly Coordinated Group 14 and 15 Chalcogenites

The synthesis of N -> M intramolecularly coordinated group 14 and 15 chalcogenites is reported. The N -> Sn intramolecularly coordinated organotin(IV) carbonate L(Ph)SnCO3 (1), where L is the N,C,N-chelating ligand 2,6-(Me2NCH2)(2)C6H3-, reacts with SO2 and SeO2 to provide the organotin(IV) sulfite L(Ph)SnSO3 (4) and selenite [L(Ph)SnSeO3](2) (5), respectively. Treatment of [LSbO](2) (2) and [LBiO](2) (3) with SeO2 provided the organoantimony and bismuth selenites LSbSeO3 (6) and [LBiSeO3](3) (7), respectively. Compounds 5-7 are rare examples of mixed element oxides with well-defined stoichiometry MSeO3 (M = Sn, Sb, Bi). Compounds 4-7 were characterized by means of elemental analyses, H-1, C-13, Se-77, and Sn-119 NMR spectroscopies, IR spectroscopy, and single-crystal X-ray diffraction analysis.
