The asymmetric unit of the title compound, C(15)H(15)N(3)O(2), comprises two crystallographically independent mol-ecules (A and B), each having an E conformation around the C=N bond. In each mol-ecule, there is an intra-molecular O-H⋯N hydrogen bond making an S(6) ring motif. The dihedral angles between the substituted phenyl rings are 17.49 (9) and 10.03 (9)°. In the crystal, N-H⋯O hydrogen bonds link neighbouring independent mol-ecules into infinite chains, of the type -A-B-A-B-, along the a axis, enclosing R(2) (1)(7) ring motifs. The chains are linked by N-H⋯O hydrogen bonds and C-H⋯O inter-actions, leading to the formation of a three-dimensional network.
标题化合物C(15)H(15)N(3)O(2)的不对称单元包含两个晶体学独立的分子（A和B），每个分子在C=N键周围均具有E构型。在每个分子中，存在一个分子内O-H⋯N氢键，形成一个S(6)环模式。取代苯环之间的二面角分别为17.49 (9)°和10.03 (9)°。在晶体中，N-H⋯O氢键将相邻的独立分子沿a轴连接成-A-B-A-B-型的无限链，形成R(2) (1)(7)环模式。这些链通过N-H⋯O氢键和C-H⋯O相互作用相连，导致形成三维网络。
