Description
Summary:The title benzohydrazide derivative, C17H18N2O5, 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 methoxy groups at the meta positions of the trimethoxybenzene group are almost coplanar with the ring [C—O—C—C = 1.62 (16) and 178.33 (10)°], whereas the third methoxy group, at the para position, is (+)-synclinal with the ring. In the crystal, molecules are linked by N—H...O and bifurcated O—H...(N,O) hydrogen bonds, as well as weak C—H...O interactions, into sheets lying parallel to the ac plane. A C—H...π interaction also occurs.
