Crystal structure of 3-amino-5,5-dimethyl-2-[(E)-2-nitroethenyl]cyclohex-2-en-1-one

Abstract

The asymmetric unit of the title compound, C10H14N2O3, contains two independent molecules with similar conformations. In the both molecules, the cyclohexene rings adopt the same envelope conformation with the flap C atoms lying 0.658 (3) and 0.668 (3) Å from the mean planes formed by the remaining atoms. In the crystal, adjacent molecules are connected via N—H...O hydrogen bonds and weak C—H...O interactions, forming supramolecular layers parallel to (-101).
