N′-[(E)-4-(Dimethylamino)benzylidene]-2-(5-methoxy-2-methyl-1H-indol-3-yl)acetohydrazide

In the title compound, C21H24N4O2, inversion-related molecules are linked into dimers through pairs of N—H...O hydrogen bonds, which generate R22(8) motifs. As well as dimer formation, an additional N—H...O hydrogen bond and two C—H...π contacts, involving H atoms from the phenyl ring and the pyrrole and benzene rings of the indole system, generate a three-dimensional network.
