摘要：
In the title compound, C21H16N2O2, the five-membered heterocyclic ring makes a dihedral angle of 47.06 (6)degrees with the attached benzene ring, whereas the indan-1,3-dione ring system and the benzene ring are oriented at a dihedral angle of 21.92 (7)degrees. In the crystal, inversion dimers linked by pairs of C-H center dot center dot center dot O hydrogen bonds generate R-2(2)(22) loops. Aromatic pi-pi stacking interactions [centroid-centroid distances = 3.8325 (12)-3.8600 (12) angstrom] also occur.
