3-Methyl-1,5-dinitro-9-phenacyl-3-azabicyclo[3.3.1]non-7-en-6-one

Abstract

There are two mol­ecules, A and B, in the asymmetric unit of the title compound, C34H34N6O12. In both mol­ecules, the eight‐membered ring has a conformation which is close to a boat—boat conformation and the cyclo­hexene ring is characterized by a sofa conformation. The nitro groups in each mol­ecule are situated in equatorial positions. Both nitro groups of mol­ecule A are considerably rotated with respect to the flattened fragment of the cyclo­hexene ring. The same is true for one of the nitro groups of mol­ecule B, whereas the other such group in mol­ecule B is almost coplanar with the corresponding fragment.
