چکیده
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.
