Abstract

The title compound, C(15)H(21)NO(4)S, crystallized with two independent mol-ecules in the asymmetric unit in which the dihedral angles between the mean planes of the benzene and cyclo-hexane rings are 78.3 (2) and 67.6 (2)°. The substituents of the cyclo-hexyl rings are in equatorial orientations. In the crystal, both mol-ecules form R(2) (2)(6) carb-oxy-lic acid inversion dimers via pairs of O-H⋯O hydrogen bonds. Further N-H⋯O and C-H⋯O inter-actions generate a three-dimensional network.

Geometry. Bond distances, angles etc. have been calculated using the rounded fractional coordinates. All su's are estimated from the variances of the (full) variance-covariance matrix. The cell e.s.d.'s are taken into account in the estimation of distances, angles and torsion angles
Refinement. Refinement on F2 for ALL reflections except those flagged by the user for potential systematic errors. Weighted R-factors wR and all goodnesses of fit S are based on F2, conventional R-factors R are based on F, with F set to zero for negative F2. The observed criterion of F2 > σ(F2) is used only for calculating -R-factor-obs etc. and is not relevant to the choice of reflections for refinement. R-factors based on F2 are statistically about twice as large as those based on F, and R-factors based on ALL data will be even larger.
