eng	Syntheses and structures of N,C,N-stabilized antimony chalcogenides	The oxidation reactions of ArSb [Ar = 2,6-( HC=N-t- Bu)(2)C6H3] with S-8, grey Se and Te as well as E2Ph2 (E== S, Se, Te) are demonstrated. The reactions of ArSb with elemental sulfur and selenium occurred at elevated temperatures and yielded ArSbE (E== S, 1; Se 2), whereas the reactions with E2Ph2 proceeded at room temperature with subsequent formation of the corresponding insertion complexes ArSb(EPh) 2 (E==S 3; Se 4). In addition, ArSb(TePh)(2) (5) was formed at very low temperature and showed a temperature-dependent reversible equilibrium with ArSb and Te2Ph2 between -80 degrees C and 20 degrees C. The formation and structure of compounds 1-4, which were isolated in good yields, are assigned through multinuclear NMR (H-1, C-13, Se-77), IR spectroscopy and microanalyses data. In addition, the molecular structures of 2-4 are further confirmed by single crystal X-ray diffraction studies.	Syntheses; structures; N,C,N-stabilized; antimony; chalcogenides
