Theoretical and Experimental Studies of Six-Membered Selenium-Sulfur Nitrides SexS4-xN2 (x = 0-4). Preparation of S4N2 and SeS3N2 by the Reaction of Bis(bis(trimethylsilyl)amino)sulfane with Chalcogen Chlorides.
-Structural and stability relationships of the members of the series 1, 3-SexS4-xN2 (x = 0-4) are determined by ab initio MO calculations. The stability of the molecules decreases with increasing Se content. This explains that Se-rich molecules are not isolated. Within a given chemical composition, isomers containing a N=Se=N unit (e.g. (VIII)) are higher in energy than those with a N=S=N unit, e.g. (VI) and (VII) in the case of SeS3N2. The IR, Raman, and NMR results indicate the formation of (VI) in the latter case. - (MAANINEN, A.;
