N'-(4-Meth-oxy-benzyl-idene)-4-methyl-benzohydrazide.

The title compound, C(16)H(16)N(2)O(2), is the product of the reaction of 4-meth-oxy-benzaldehyde and 4-methyl-benzo-hydrazide. The dihedral angle between the substituted benzene rings is 17.6 (3)° and the meth-oxy C atom is almost coplanar with its attached ring [deviation = 0.019 (4) Å]. In the crystal, mol-ecules are linked by N-H⋯O hydrogen bonds, forming C(4) chains propagating along the b-axis direction.

N'-(2-Hy-droxy-benzyl-idene)-3-methyl-benzohydrazide.

The title compound, C(15)H(14)N(2)O(2), is the product of the reaction of 2-hy-droxy-benzaldehyde and 3-methyl-benzo-hydrazide. The dihedral angle between the substituted benzene rings is 19.5 (3)° and an intra-molecular O-H⋯N hydrogen bond generates an S(6) ring motif. In the crystal, mol-ecules are linked by N-H⋯O hydrogen bonds to generate C(4) chains propagating in [001] and C-H⋯O inter-actions to the same O-atom acceptor reinforce the chains.
