Abstract

The crystal structure of the title compound has been determined by the heavy-atom method from 1 113 observed three-dimensional photographic data. Crystals are monoclinic with a=17.05, b=7.11, c=17.10 Å(all ±0.02 Å), β=89.0 (0.2)° , space group C2/c, with Z= 8. The structure was refined by block-diagonal least-squares to R 0.098. There is an intermolecular hydrogen bond of the N-H … O type. The cyclohexane portion of the molecule adopts a slightly distorted chair conformation.
