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.
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.
