The reactions of sulphur–nitrogen species in liquid ammonia
Abstract
14 N N.m.r. spectroscopy reveals that liquid ammonia solutions of [S4N3]Cl or [S3N2Cl]Cl contain S3N3– whilst solutions of S4N4 contain S3N3– and S4N5– and traces of other species such as S2N22–; the usefulness of these liquid ammonia solutions in synthesis has been established in several cases with two new complexes being characterised by X-ray crystallography.
