| dc.description | The title molecule, C20H21NO6, adopts a keto–amine tautomeric form. An intramolecular N—H⋯O hydrogen bond, classified as a resonanse-assisted hydrogen bond, influences the molecular conformation; the two benzene rings form a dihedral angle of 24.6 (1)°. In the crystal structure, weak intermolecular C—H⋯O hydrogen bonds link molecules into chains propagating along [001]. | pl_PL |
