title: (E)-1-(2-Nitro-ethen-yl)naphthalene.
abstract: 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.
