4-Methyl-2-oxo-2H-chromen-7-yl 4-fluoro­benzene­sulfonate

In the asymmetric unit of the title compound, C(16)H(11)FO(5)S, the 2H-chromene ring is essentially planar, with a maximum deviation of 0.040 (2) Å. The dihedral angle between the 2H-chromene ring and the 4-fluoro­phenyl ring is 2.17 (8)°. One of the sulfonamide O atoms is approximately coplanar wit...

Sumario:In the asymmetric unit of the title compound, C(16)H(11)FO(5)S, the 2H-chromene ring is essentially planar, with a maximum deviation of 0.040 (2) Å. The dihedral angle between the 2H-chromene ring and the 4-fluoro­phenyl ring is 2.17 (8)°. One of the sulfonamide O atoms is approximately coplanar with the benzene ring [C—C—S—O torsion angle = 166.00 (14)°], whereas the other O atom lies well below the plane [C—C—S—O = −61.35 (17)°]. In the crystal, mol­ecules are connected by weak C—H⋯O hydrogen bonds, forming two-dimensional networks parallel to the ac plane.
