Abstract
The title compound, C15H21NO4S, crystallized with two independent molecules in the asymmetric unit in which the dihedral angles between the mean planes of the benzene and cyclohexane rings are 78.3 (2) and 67.6 (2)°. The substituents of the cyclohexyl rings are in equatorial orientations. In the crystal, both molecules form R22(6) carboxylic acid inversion dimers via pairs of O—H⋯O hydrogen bonds. Further N—H⋯O and C—H⋯O interactions generate a three-dimensional network.
