The reaction of tetrasulphur tetranitride with diselenium dichloride in thionyl chloride

Abstract

Tetrasulphur tetranitride reacts with thionyl chloride to form thiotrithiazyl chloride (S₄N₃Cl) and thiodithiazyl dioxide (S₃N₂O₂). The reaction between tetrasulphur tetranitride and diselenium dichloride in the presence of thionyl chloride gives thiotrithiazyl chloride and a compound (SeS₂N₂Cl₂)_n tentatively proposed as selenotrithiazyl hexachloroselenate ([SeS₃N₃]₂SeCl₆). The infrared spectrum of (SeS₂N₂Cl₂)_n is reported.
