| Summary: | 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 R2
2(8) and R2
2(10) loops. The chains are
further connected by �–� stacking interations, with centroidto-
centroid distances of 3.9050 (7) A ° , forming layers parallel
to the b axis. |
