(E)-4-Meth-oxy-N'-(3,4,5-trimeth-oxy-benzyl-idene)benzohydrazide.

ABSTRACT: In the asymmetric unit of the title compound, C(18)H(20)N(2)O(5), there are two crystallographic independent mol-ecules. Both mol-ecules are twisted; the dihedral angle between the two benzene rings is 7.2?(5)° in one mol-ecule, whereas it is 85.9?(4)° in the other. Of the three meth-oxy groups in the 3,4,5-trimeth-oxy-phenyl unit, two meth-oxy 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 meth-oxy, at the para position, is out of the plane [C-O-C-C of 72.8?(9)° in one mol-ecule and -77.5?(9)° in the other]. In the crystal, mol-ecules are linked by N-H?O hydrogen bonds and weak C-H?O inter-actions into tapes along the b axis. C-H?? inter-actions are also present.
