The preparation and properties of sulphur nitride and thiotrithiazyl chloride

Abstract

1. It is shown that acetyl chloride reacts with sulphur nitride to give diacetamide, sulphur dioxide, and possibly sulphur chlorides, as well as thiotrithiazyl chloride. 2. Hydrogen chloride alone, reacts with sulphur nitride to form thiotrithiazyl chloride. Its preparation from acetyl chloride and sulphur chloride, is presumably due to the small amount of free hydrogen chloride always present in these reagents. 3. Hydrogen bromide and hydrogen iodide react with sulphur nitride also, apparently forming thiotrithiazyl bromide, and thiotrithiazyl iodide respectively. 4. Thiotrithiazyl chloride is easily decomposed by methyl alcohol and ethyl acetate to reform sulphur nitride. 5. Several proposed structures for sulphur nitride are discussed. A tetrahedral structure for sulphur nitride is suggested, which agrees with its chemical properties and also with modern X-ray data.
