ABSTRACT
In the title coumarin derivative, C28H26N2O2, the coumarin unit is approximately planar, with a maximum deviation of 0.048â
(3)â
Å. The central benzene ring is oriented at dihedral angles of 30.15â
(14) and 10.51â
(11)°, respectively, to the pyridine ring and coumarin ring system. In the crystal, weak C-Hâ¯O and C-Hâ¯N hydrogen bonds and weak C-Hâ¯π inter-actions link the mol-ecules into a three-dimensional supra-molecular architecture.
