title: Crystal structure of 3-{(E)-[(3,4-di-chloro-phen-yl)imino]-meth-yl}benzene-1,2-diol.
abstract: In the title Schiff base, C13H9Cl2NO2, which arose from the condensation of 3,4-di-chloro-aniline with 2,3-di-hydroxy-benzaldehyde, the dihedral angle between the aromatic rings is 44.74 (13)°. Intra-molecular O-H⋯O and O-H⋯N hydrogen bonds close S(5) and S(6) rings, respectively. In the crystal, inversion dimers linked by pairs of O-H⋯O hydrogen bonds generate R 2 (2)(10) loops. A weak C-H⋯π inter-action is also observed.
