There are three independent mol-ecules in the asymmetric unit of the title compound, C(19)H(16)N(2)O(3), in which the dihedral angles between the naphthalene ring system and the benzene ring are 7.52 (16), 18.15 (18), and 13.9 (2)°. All the mol-ecules exist in the trans configuration with respect to the methyl-idene units. In each mol-ecule there is one O-H⋯N and one N-H⋯O intra-molecular hydrogen bond. In the crystal, two of the mol-ecules are linked via a bifurcated N-H⋯(O,O) hydrogen bond. All three mol-ecules are further linked via C-H⋯O inter-actions.
标题化合物C(19)H(16)N(2)O(3)的不对称单元中有三个独立分子,其中萘环系统与苯环之间的二面角分别为7.52 (16)°、18.15 (18)°和13.9 (2)°。所有分子相对于亚甲基单元均以反式构型存在。每个分子中存在一个O-H⋯N和一个N-H⋯O分子内氢键。在晶体中,其中两个分子通过一个分叉的N-H⋯(O,O)氢键相连。所有三个分子还通过C-H⋯O相互作用进一步相连。
