Some reactions of cyclotetrathiatriazenium chloride (S4N3Cl) vapour at hot metal (iron, titanium, or silver) surfaces. An alternative route form S4N3Cl and silver to disulphur dinitride and hence poly(sulphur nitride)

Abstract

Cyclotetrathiatriazenium chloride (thiotrithiazyl chloride, S₄N₃Cl) vaporized at ca. 130 °C reacts with (i) iron, (ii) titanium, and (iii) silver (at ca. 300 °C) to give respectively (i) S₃N₂Cl, S₄N₄, and (NSCl)₃, (ii) sulphur, nitrogen, and TiCl₄, and (iii) S₂N₂, Ag₂S, and AgCl, as the major products. The isolation of S₂N₂ from the silver reaction and its polymerization to poly (sulphur nitride) and also described.
