(E)-4-Hydroxy-N′-(4-hydroxy-3-methoxybenzylidene)benzohydrazide
In the title compound, C(15)H(14)N(2)O(4), the N=C double bond has an E configuration. The two benzene rings make a dihedral angle of 28.59 (6)°. In the crystal, mol-ecules are linked into a three-dimensional network by inter-molecular N-H⋯O, O-H⋯O and C-H⋯O hydrogen bonds and stabilized by weak C-H⋯π inter-actions.

The title p-hy-droxy Schiff base, C17H17NO4, was synthesized via the condensation reaction of benzocaine with vanillin. The benzyl-idine and benzoate rings are inclined to one another by 24.58 (8)°, and the conformation about the C=N bond is E. In the crystal, mol-ecules are linked by O-H⋯N hydrogen bonds, forming zigzag chains propagating along [010]. Adjacent chains are linked by C-H⋯π and we...
