✦ Synopsis

The title compound, C 20 H 15 N 3 O 3 , consists a phthalonitrile group and an isoindole-1,3-dione group connected by a flexible butoxy chain. The dihedral angle between these two groups is 70.47 (3) . Partial face-to-face overlap between the phthalonitrile groups of centrosymmetrically related molecules is observed. In addition, the crystal packing is stabilized by C-HÁ Á ÁO hydrogen bonds.
