2-Chloro-3-[(E)-(hydrazin-1-yl­idene)meth­yl]-6-meth­oxy­quinoline

In the title compound, C₁₁H₁₀ClN₃O, the quinoline ring system is essentially planar, the r.m.s. deviation for the non-H atoms being 0.014 (2) Å with a maximum deviation from the mean plane of 0.0206 (14) Å for the C atom bonded to the –CH—N=NH₂ group. In the crystal, molecules are linked via N—H...O and N—H...N hydrogen bonds, forming zigzag layers parallel to (010).
