In the title compound, C(17)H(18)N(2)O(4), the azomethine double bond adopts an E conformation with an N-N-C-C torsion angle of -178.3 (3)°. The benzene rings are almost coplaner, with a dihedral angle of 2.98 (14)° between their mean planes. In the crystal, the molecules are linked by N-H⋯O hydrogen bonds, resulting in chains of mol-ecules lying parallel to the b axis. The structure is further consolidated by rather weak C-H⋯O hydrogen-bonding inter-actions, resulting in six-membered rings about inversion centers linked into chains arranged parallel to the b axis.
在标题化合物C(17)H(18)N(2)O(4)中，偶氮甲碱双键呈E构象，N-N-C-C扭转角为-178.3 (3)°。苯环几乎共面，其平均平面之间的二面角为2.98 (14)°。在晶体中，分子通过N-H⋯O氢键相连，形成平行于b轴的分子链。结构通过相当弱的C-H⋯O氢键相互作用进一步巩固，形成围绕反演中心的六元环，这些环连接成平行于b轴排列的链。
