The mol­ecule of the title compound, C9H5Cl2NO, is essentially planar [give maximum or r.m.s. deviation] and the hydr­oxy group acts as a hydrogen-bond donor to the N atom of a symmetry-related mol­ecule, generating a hydrogen-bonded dimer,which lies on a twofold rotation axis.

Partial Text

Unlike quinolin-8-ol, which yields a large number of metal derivatives, 5,7-dichloro­quinolin-8-ol forms only a small number of metal chelates. For their crystal structures, see: García-Granda et al.
