N′-(4-Hydroxy­benzyl­idene)-4-meth­oxybenzohydrazide

The title compound, C(15)H(14)N(2)O(3), was prepared by the reaction of 4-hydroxy­benzaldehyde and 4-methoxy­benzohydrazide in methanol. The dihedral angle between the two benzene rings is 6.8 (1)°. The meth­oxy group is disordered over two orientations with occupancies of ca 0.63 and 0.37. In the major disorder component, the meth­oxy group is coplanar with the attached ring. In the crystal structure, the mol­ecules are linked into a three-dimensional framework by inter­molecular O—H⋯O and N—H⋯O hydrogen bonds.
