In the mol-ecule of the zwitterionic title compound, C(17)H(11)N(3)O, 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 intra-molecular N-H⋯O hydrogen bond results in the formation of a planar six-membered ring. In the crystal structure, inter-molecular C-H⋯O inter-actions link the mol-ecules into centrosymmetric dimers.
在两性离子标题化合物C(17)H(11)N(3)O的分子中，萘环体系是平面的[最大偏差 = 0.029 (3) Å]，相对于苯环的二面角为3.55 (3)°。分子内N-H⋯O氢键导致形成一个平面六元环。在晶体结构中，分子间C-H⋯O相互作用将分子连接成中心对称的二聚体。
