چکیده
The title mol-ecule, C(12)H(9)NO(2), adopts a trans configuration about the olefinic double bond. The dihedral angle between the naphthalene ring system (r.m.s. deviation = 0.012 Å) and the nitro-ethenyl group (r.m.s. deviation = 0.032 Å) is 12.66 (5)°. The mol-ecules are linked into a two-dimensional network parallel to the bc plane by C-H⋯O hydrogen bonds. The substituted benzene rings in adjacent networks are stacked with a centroid-centroid distance of 3.6337 (11) Å, indicating π-π inter-actions.

The asymmetric unit of the title compound, C10H14N2O3, contains two independent mol-ecules with similar conformations. In the both mol-ecules, the cyclo-hexene 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 mol-ecules are connected via N-H⋯O hydrogen bonds and weak C-H⋯...

The title compound, C(6)H(5)NO(3), crystallizes in the triclinic system with six independent mol-ecules in the asymmetric unit. In a previous study, the structure of the title compound was determined in the monoclinic P2(1)/n space group at 100 K [Valerga et al. (2009 ▶). Acta Cryst. E65, o1979]. All six independent mol-ecules display an E configuration about the C=C double bond, with the dihed...
