The structure of the dimeric oxime compound obtained by the reaction of 2-chlorocyclohexanone oxime or 1-chloro-2-nitrosocyclohexane dimer with stoichiometrical ammonia was established to be 14-oxa-7,15,16-triazatetracyclo[11.2.1.01,6.08,13]hexadecan-16-ol by spectroscopic methods and X-ray crystallography; the result leads to a revision of the previously proposed structure, bis(2-hydroxyiminocyclohexyl)amine.
