In the title compound, C18H14N2O3, the dihedral angle between the naphthalene ring system and the benzene ring is 59.99 (13)°. A short intramolecular C—H⋯N contact closes an S(6) ring. The nitro group is disordered over two orientations in a statistical ratio. In the crystal, weak C—H⋯O hydrogen bonds and very weak π–π stacking interactions [centroid–centroid separation = 3.9168 (17) Å] are observed.

Schiff bases are considered an important class of organic compounds, which have wide applications. In recent years, they have gained significant interest in the area of drug research and development owing to the broad bioactivities such as insecticidal, antibacterial, antituberculosis and antimicrobial reported for the compounds and their metal complexes. These compounds play an important role in biological systems and are observed in various enzymes such as transaminases, tryptophan synthase etc. The important physical and biological properties of these compounds are related to the presence of the intramolecular hydrogen bond and proton transfer equilibrium.
have also been utilized as ligands to synthesize metal complexes with interesting applications. The steric and inductive effects introduced by substituents present on the aromatic portion of the Schiff base can influence the properties of the ligand significantly. In continuation of our efforts in understanding the role of subtle electronic variations such as substituent effects on Chemistry and activity of and their metal complexes, we herein report the of Schiff base derived from 3-nitroaniline and 2-methoxy naphthaldehyde (Tolulope et al., 2013).The molecule of title compound is non-planar, with a dihedral angle between the naphthyl and phenyl aromatic rings of 59.99 (13)°, in which the two rings are twisted from one another. The C9—O3 single bond of 1.358 (3) Å and the C7═N2 double bond of 1.261 (3) Å .The bond angle of C5—N2—C7 of the imine group is 117.5 (2)°, less than 120°. The bond length of the nitro group is N1—O2(1.241 (6)Å) and N1—O1(1.239 (6)Å) and bond angle in O2—N1—O1 is 123.4 (12)° which is more than the planar bond angle of 120°. The torsion angles C8—C7—N2—C5 is 178.1 (2)°.These values support that the configurations about the N2=C7 bond is anti(E-form), which is in accordance with the enol-imine tautomeric form.
The title compound has an intra molecular C16— H16···N2 hydrogen bond forming an S(6) motif (Table 2). Also there is a C—H···O intermolecular interaction, in which a C—H of the naphthyl ring of one molecule and O-atom of the nitro group of another molecule are linked to one another.
The block-like, yellow single crystals of the compound C18 H14 N2 O3, were grown using 1:1 mixture of CHCl3 and methanol as solvent by slow evaporation technique.
The hydrogen atoms in the structure were positioned geometrically (C—H = 0.93–0.98 Å. N—H = 0.86Å) and were refined using a riding model with Uiso(H) = xUeq(C,N), where x = 1.5 for methyl and 1.2 for all other atoms. The two oxygen atoms of the nitro group are disordered over two orientations. The SADI, SIMU, and ISOR commands in SHELXL (Sheldrick, 2015) were used to model the disorder.

Geometry. All e.s.d.'s (except the e.s.d. in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell e.s.d.'s are taken into account individually in the estimation of e.s.d.'s in distances, angles and torsion angles; correlations between e.s.d.'s in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell e.s.d.'s is used for estimating e.s.d.'s involving l.s. planes. |
