Ethyl 3-oxo-3H-benzo[f]chromene-2-carboxyl-ate

Ethyl 3-oxo-3H-benzo[f]chromene-2-carboxyl-ate

In the title compound, C(16)H(12)O(4), the chromene ring system is almost planar [maximum deviation = 0.026 (1) Å] and makes dihedral angles of 1.24 (9) and 26.5 (2)° with the fused benzene ring and the plane of the ethyl carboxyl-ate group, respectively.
