Abstract
In the crystal structure of the title compound, C21H17NO3, the dibenzo–isoquinoline–dione unit has a planar structure, the maximum atomic deviation being 0.091 (3) Å. The crystal structure is stabilized by π–π stacking [centroid–centroid distance = 3.851 (2) Å] and intermolecular N—H⋯O hydrogen bonding.

As part of our work involving the synthesis of a series of azonafide analogues from 1,3,4(2H)-isoquinolinetrione we report the crystal structure of the title compound (Fig. 1)
R-factors based on F2 are statistically about twice as large as those based on F, and R- factors based on ALL data will be even larger
Summary
R factor = 0.066; wR factor = 0.077; data-to-parameter ratio = 13.1. In the crystal structure of the title compound, C21H17NO3, the dibenzo–isoquinoline–dione unit has a planar structure, the maximum atomic deviation being 0.091 (3) Å. The crystal structure is stabilized by – stacking [centroid–centroid distance = 3.851 (2) Å] and intermolecular N—H O hydrogen bonding.
