Abstract: The title compound {systematic name: 4-methyl-2-oxo-2H-1-benzopyran-7-yl 3-[4-(dimethylamino)phenyl]prop-2-enoate}, C₁₉H₁₃ClO₄, has an E configuration and the dihedral angle between the coumarin unit and the benzene ring is 81.70 (6)°. The molecules are linked by two C-HO hydrogen bonds into a C(4)C(6)[R₂¹(6)] chain of rings. Adjacent chains are linked by C-HO hydrogen bonds rings into stepped sheets. Adjacent sheets are linked by weak C-HO hydrogen bonds into a three-dimensional network.
