title: (E)-N'-(2,5-Dimethoxy-benzyl-idene)-2-(8-quinol-yloxy)acetohydrazide methanol solvate.
abstract: The two mol-ecules in the asymmetric unit of the title compound, C(20)H(19)N(3)O(4)·CH(4)O, are paired via O-H⋯(O,N), N-H⋯O, and C-H⋯O hydrogen bonds. The mol-ecular skeleton of the acetohydrazide mol-ecule is close to planar; the benzene and quinoline mean planes form a dihedral angle of 3.9 (3)°. The crystal packing exhibits weak inter-molecular C-H⋯O hydrogen bonds and π-π inter-actions, indicated by short distances of 3.668 (3) Å, between the centroids of N-containing six-membered rings from neighbouring acetohydrazide mol-ecules.
