چکیده
The title benzohydrazide derivative, C(17)H(18)N(2)O(5), exists in a trans conformation with respect to the C=N double bond. The dihedral angle between the benzene rings is 19.41 (5)°. The two meth-oxy groups at the meta positions of the trimeth-oxy-benzene group are almost coplanar with the ring [C-O-C-C = 1.62 (16) and 178.33 (10)°], whereas the third meth-oxy group, at the para position, is (+)-synclinal with the ring. In the crystal, mol-ecules are linked by N-H⋯O and bifurcated O-H⋯(N,O) hydrogen bonds, as well as weak C-H⋯O inter-actions, into sheets lying parallel to the ac plane. A C-H⋯π inter-action also occurs.
