4-Hydroxy-<i>N</i>′-[(<i>E</i>)-(2-hydroxyphenyl)methylidene]benzohydrazide

Abstract

In the title compound, C14H12N2O3, the dihedral angle between the two benzene rings is 21.70 (4)°. An intra­molecular O—H⋯N hydrogen bond generates an S(6) ring motif. In the crystal structure, the mol­ecules are linked by inter­molecular O—H⋯O, N—H⋯O and C—H⋯O hydrogen bonds into a three-dimensional framework.
