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

In the asymmetric unit of the title compound, C18H20N2O5, 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 t...
