✦ Synopsis

In the title compound, C 19 H 28 BrNO 3 , which crystallizes with two molecules in the asymmetric unit, the six-membered cyclohexanone ring exists in a sightly distorted chair conformation. The bromo and methoxyethoxy groups are oriented axially, whereas the phenyl group and tert-butyl adopt equatorial positions. The crystal structure is stabilized by O-HÁ Á ÁO intermolecular hydrogen bonds.

The title compound, C 11 H 14 N 2 O 5 , was prepared by the reaction of HNO 3 and 1-tert-butyl-4-methoxybenzene. The atoms of the benzene ring, the nitro N atoms, the methoxy O atom and the tert-butyl tertiary C atom are coplanar; the dihedral angles between this plane and the NO 2 planes are 50.41
