Abstract: In the title compound, C₂₇H₂₂N₂O₄, the dihedral angles between the central benzene ring and the cyanobenzene ring and the 2H-coumarin ring system (r.m.s. deviation = 0.014 Å) are 22.95 (11) and 75.59 (8)°, respectively. Both terminal C atoms of the pendant diethylamino group lie to the same side of the coumarin ring system [deviations = 1.366 (2) and 1.266 (2) Å]. In the crystal, molecules are linked by C-HO and C-HN hydrogen bonds and a C-H [pi] interaction, generating a three-dimensional network.
