4-Methyl-2-oxo-2H-chromen-7-yl 4-fluoro-benzene-sulfonate.


ABSTRACT: 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-fluoro-phenyl 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, mol-ecules are connected by weak C-H?O hydrogen bonds, forming two-dimensional networks parallel to the ac plane.
