Synthesis and structure
It is prepared by reaction of disulfur dichloride with ammonia, although other methods have been developed. Together with, the reaction also produces three isomers of and two isomers of .Azacyclooctasulfane is an analogue of octasulfur, with one replaced by. The center is almost planar, suggesting that the amine is nonbasic.
