organic compounds
The title compound, C20H15N3O3, 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—HO hydrogen bonds.
