7-Chloro-4-[(E)-2-(3,4,5-trimeth-oxy-benzyl-idene)hydrazin-1-yl]quinoline.

In the title compound, C(19)H(18)ClN(3)O(3), the r.m.s. deviation through the 23 non-H and non-meth-oxy atoms is 0.088 Å, indicating a planar mol-ecule with the exception of the meth-oxy groups. One meth-oxy group, surrounded on either side by the other meth-oxy groups, is almost normal to the benzene ring to which it is connected [C-O-C(ar)-C(ar) torsion angle = 81.64 (15)°]. In the crystal, N-H⋯O, C-H⋯O and π-π inter-actions [between quinoline residues; centroid-centroid distance = 3.4375 (8) Å] link mol-ecules into a three-dimensional architecture.
