Deskripsi
In the title coumarin derivative, C28H26N2O2, the coumarin unit is approximately planar, with a maximum deviation of 0.048 (3) Å. The central benzene ring is oriented at dihedral angles of 30.15 (14) and 10.51 (11)°, respectively, to the pyridine ring and coumarin ring system. In the crystal, weak C—H...O and C—H...N hydrogen bonds and weak C—H...π interactions link the molecules into a three-dimensional supramolecular architecture.
