Abstract: The indolyl -NH group of the title Schiff base, C19H19N3O2, forms a hydrogen bond to the -OH group of an inversion-related molecule, resulting in a hydrogen-bonded dimer; adjacent dimers are further linked through an interdimer N-HO hydrogen bond involving the -C(=O)-NH-N=fragment to form a linear ribbon that runs along the a axis.
