In the zwitterionic title compound, C(16)H(12)N(2)O, the dihedral angle between the benzene ring and naphthalene ring system is 2.0 (1)°. The azo group adopts a trans configuration and an intra-molecular N-H⋯O hydrogen bond is found. In the crystal, the mol-ecules are packed by strong π-π inter-actions [centroid-centroid distance between aromatic rings = 3.375 (3) Å].
在两性离子标题化合物C₁₆H₁₂N₂O中，苯环与萘环系统之间的二面角为2.0 (1)°。偶氮基团呈反式构型，并且存在分子内N-H⋯O氢键。在晶体中，分子通过强π-π相互作用堆积[芳香环之间的质心-质心距离 = 3.375 (3) Å]。
