title: (E)-3-[2-(4-Chloro-phenyl-sulfon-yl)vin-yl]-6-methyl-4H-chromen-4-one.
abstract: In the title compound, C(18)H(13)ClO(4)S, the mean planes of the chloro-phenyl ring and the S-C=C-C chain are oriented at angles of 52.7 (2) and 51.3 (2)°, respectively, with respect to the sulfonyl (O=S=O) plane. The dihedral angle between the mean planes of the chloro-phenyl group and the benzopyran ring is 80.7 (1)°. The crystal structure is stabilized by two inter-molecular C-H⋯O inter-actions, forming centrosymmetrc dimers, which are linked via a second C-H⋯O inter-action into a chain structure.
