2-{[2-(4-Chloro-phen-yl)hydrazinyl-idene]meth-yl}phenol

In the title Schiff base mol-ecule, C(13)H(11)ClN(2)O, the non-H atoms are approximately coplanar (r.m.s. deviation = 0.115 Å) and the two benzene rings are twisted by 9.36 (3)° with respect to each other. The hy-droxy group is hydrogen bonded to the azomethine N atom. In the crystal, an N-H⋯π inter-action is observed between the imino group and the hy-droxy-benzene ring of an adjacent mol-ecule.
