title: (E)-N'-(5-Chloro-2-hy-droxy-benzyl-idene)-2,4-dihy-droxybenzohydrazide methanol monosolvate.
abstract: In the title compound, C(14)H(11)ClN(2)O(4)·CH(3)OH, the mol-ecule adopts an E conformation about the C=N bond. The compound is in the enamine-keto form. The two terminal benzene rings make a dihedral angle of 10.53 (9)°. Intra-mol-ecular O-H⋯O and O-H⋯N hydrogen bonding stabilizes the mol-ecular structure. In the crystal, O-H⋯O hydrogen bonds link the mol-ecules, forming chains running along the b axis.
