In the title compound, C(21)H(21)N(3)O(5)·CH(4)O, the quinoline plane and the benzene ring form a dihedral angle of 3.6 (2)°. The methanol solvent mol-ecule is linked with the acetohydrazide mol-ecule via O-H⋯N and N-H⋯O hydrogen bonds. In the crystal structure, weak inter-molecular C-H⋯O hydrogen bonds help to consolidate the crystal packing, which also exhibits π-π inter-actions, as indicated by short distances of 3.739 (4) Å between the centroids of the aromatic rings.
在标题化合物C₂₁H₂₁N₃O₅·CH₄O中,喹啉平面与苯环形成的二面角为3.6 (2)°。甲醇溶剂分子通过O—H⋯N和N—H⋯O氢键与乙酰肼分子相连。在晶体结构中,弱的分子间C—H⋯O氢键有助于巩固晶体堆积,晶体堆积还表现出π - π相互作用,芳香环质心之间的短距离为3.739 (4) Å表明了这一点。
