چکیده
In the title compound, C(19)H(17)N(3)O(3)·CH(4)O, the mean planes of the benzene ring and the quinoline rings make a dihedral angle of 75.5 (2)°. The acetohydrazide mol-ecules are connected via pairs of inter-molecular O-H⋯O hydrogen bonds into inversion dimers, and the methanol solvent mol-ecule is linked to the acetohydrazide mol-ecule via inter-molecular N-H⋯O and bifurcated O-H⋯(N,O) hydrogen bonds.
