Abstract

The title compound [systematic name: 3-hy­droxy-2-(4-methyl­sulfonyl-2-nitro­benzo­yl)cyclo­hex-2-enone], C14H13NO7S, is the enol form of a benzoyl­cyclo­hexa­nedione herbicide. As a result of this tautomerization, there is intra­molecular O—H⋯O hydrogen bond enclosing an S(6) ring motif. The cyclo­hexene ring has an envelope conformation, with the central CH2 C atom as the flap. Its mean plane is inclined to the benzene ring by 87.46 (8)°. In the crystal, mol­ecules are linked by a series of C—H⋯O hydrogen bonds, forming a three-dimensional framework.
