The thermal decomposition of triphenylphosphinimino-cyclotrithiazene; preparation and crystal structure of Ph3PNSNSS, a sulphur–nitrogen chain with a terminal sulphur–sulphur bond

Abstract

The thermal decomposition of Ph₃PN–S₃N₃ leads to the open-chain derivative Ph₃PNSNSS; an X-ray crystallographic analysis of the latter shows that the five atom N–S–N–S–S sequence exists in a nearly planar, cis–trans conformation.
