نویسنده
چکیده
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.
