In the molecule of the zwitterionic title compound, C17H11N3O, the naphthalene ring system is planar [maximum deviation = 0.029 (3) Å] and is oriented at a dihedral angle of 3.55 (3)° with respect to the benzene ring. An intramolecular N—H⋯O hydrogen bond results in the formation of a planar six-membered ring. In the intermolecular C—H⋯O interactions link the molecules into centrosymmetric dimers.

The title compound was prepared according to a literature method (Rădulescu et al., 2006). Crystals suitable for X-ray analysis were obtained by slow evaporation of an ethanol solution.
H atoms were positioned geometrically with N-H = 0.86 Å (for NH) and C-H = 0.93 Å for aromatic H atoms, respectively, and constrained to ride on their parent atoms, with Uiso(H) = 1.2Ueq(C,N).

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. |
Refinement. Refinement of F2 against ALL reflections. The weighted R-factor wR and goodness of fit S are based on F2, conventional R-factors R are based on F, with F set to zero for negative F2. The threshold expression of F2 > σ(F2) is used only for calculating R-factors(gt) etc. and is not relevant to the choice of reflections for refinement. R-factors based on F2 are statistically about twice as large as those based on F, and R- factors based on ALL data will be even larger. |

Azo compounds are characterized by the azo linkage (–N=N–) and are very important in the fields of dyes, pigments and advanced materials (Lee et al., 2004; Oueslati et al., 2004). We report herein the crystal structure of the title compound, obtained through the diazotization of 4-aminobenzonitrile followed by a coupling reaction with 2-naphthol.
In the molecule of the title compound (Fig. 1), the bond lengths (Allen et al., 1987) and angles are within normal ranges. Rings A (C1-C5/C10), B (C5-C10) and C (C11-C16) are, of course, planar, and they are oriented at dihedral angles of A/B = 2.32 (3), A/C = 2.58 (3) and B/C = 4.59 (3) °. The naphthalene ring system is planar with a maximum deviation of 0.029 (3) Å for atom C5. Intramolecular N-H···O hydrogen bond (Table 1) results in the formation of planar six-membered ring D (O1/N1/N2/C1/C2/H2A), which is oriented with respect to rings A, B and C at dihedral angles of A/D = 1.12 (3), B/D = 3.29 (3) and C/D = 1.47 (3) °. So, rings A, B, C and D are almost coplanar.
In the crystal structure, intermolecular C-H···O interactions link the molecules into centrosymmetric dimers (Fig. 2), in which they may be effective in the stabilization of the structure.
