(E)-4-Meth­oxy-N′-(3,4,5-trimeth­oxy­benzyl­idene)benzohydrazide

In the asymmetric unit of the title compound, C(18)H(20)N(2)O(5), there are two crystallographic independent mol­ecules. Both mol­ecules are twisted; the dihedral angle between the two benzene rings is 7.2 (5)° in one mol­ecule, whereas it is 85.9 (4)° in the other. Of the three meth­oxy groups in the 3,4,5-trimeth­oxy­phenyl unit, two meth­oxy groups at meta positions are approximately coplanar with the benzene plane [C—O—C—C torsion angles of −2.3 (13)–4.8 (11)°], but the other meth­oxy, at the para position, is out of the plane [C—O—C—C of 72.8 (9)° in one mol­ecule and −77.5 (9)° in the other]. In the crystal, mol­ecules are linked by N—H⋯O hydrogen bonds and weak C—H⋯O inter­actions into tapes along the b axis. C—H⋯π inter­actions are also present.
