【 摘 要 】

In the title iso­quinoline-1,3,4-trione derivative, C18H9NO5, the five-membered ring of the indane fragment adopts an envelope conformation with the nitro­gen-substituted C atom being the flap. The planes of the indane benzene ring and the iso­quinoline-1,3,4-trione ring make a dihedral angle of 82.06 (6)°. In the crystal, mol­ecules are linked into chains extending along the bc plane via C—H⋯O hydrogen-bonding inter­actions, enclosing R22(8) and R22(10) loops. The chains are further connected by π–π stacking inter­ations, with centroid-to-centroid distances of 3.9050 (7) Å, forming layers parallel to the b axis.
