Synthese, Strukturen und Eigenschaften von Cl 2 TeSeN 2 S und [Se 2 N 2 S] 2 2+ [XSO 3 − ] 2 (X = F, CF 3 )

Synthesis, Structures, and Properties of Cl 2 TeSeN 2 S and [Se 2 N 2 S] 2 2+ [XSO 3 − ] 2 (X = F, CF 3 ) Treatment of Se(NSO) 2 with TeCl 4 provides the colvalent five‐membered ring species ( 1 ). Reaction of Se(NSO) 2 with XSO 3 H (X = F or CF 3 ) leads to bis(1,3,4,2,5‐thiadiselenadiazolium) cations with the anions FSO 3 − ( 2a ) and CF 3 SO 3 − ( 2b ). X‐ray structure analyses for 1 and 2b are presented.
