7-Di-ethyl-amino-3-{(E)-4-[(E)-2-(pyridin-4-yl)ethen-yl]styr-yl}-2H-chromen-2-one.


ABSTRACT: 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?? inter-actions link the mol-ecules into a three-dimensional supra-molecular architecture.
