چکیده
In the title compound, C(18)H(14)N(4)O(4)·CH(3)OH, the mean planes of the benzene ring and the quinoline ring system make a dihedral angle of 15.5 (2)°. The methanol solvent mol-ecule forms an O-H⋯N hydrogen bond to the quinoline ring system and accepts an N-H⋯O hydrogen bond from the hydrazide NH group. The mol-ecules lie in layers approximately parallel to (101) and C-H⋯O inter-actions exist between mol-ecules within the layers.
