In the title molecule, C13H19NO3S, the S atom has a distorted tetrahedral geometry with an O—S—O bond angle of 120.39 (18)°. The cyclohexane ring has a chair conformation. In the crystal, molecules are connected by intermolecular N—H⋯O hydrogen bonds, forming zigzag hydrogen-bonded chains directed along the c axis.

Cylcohexylamine (0.5 g, 6.494 mmol) was taken in 50 ml round bottom flask and added 10 ml of distilled water. After 5 minutes stirring at room temperature 4-methoxy benzene sulfonyl chloride was carefully added. The pH of the reaction mixture was maintained at 8 with 10% Na2CO3 solution. After 6 h of stirring at room temperature the TLC check confirmed the completion of the reaction. The reaction mixture pH was reduced to 3 with 3 M HCl, product precipitated out was filtered and dried. Dried precipitates were dissolved in methanol for crystallization (yield: 87%).
In the last cycles of the
3 reflections (2 0 0), (1 2 0) and (0 2 0) were eliminated due to being poorly measured in the vicinity of the beam stop. The H atom of the NH group of the title compound was located in a difference map and refined with the distance restraint N—H = 0.86 (2) Å; its isotropic displacement parameter was set to be 1.2Ueq(N). The aromatic, methine, methylene and methyl H atoms were positioned geometrically with C—H = 0.93 - 0.98 Å, and allowed to ride on their parent atoms, with Uiso(H) = 1.2Ueq(C) for aromatic, methylene and methine, and 1.5Ueq(C) for methyl.Data collection: APEX2 (Bruker, 2007); cell

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. |

Sulfonamides are familiar for their enormous potential as biologically active molecules (Hanson et al., 1999; Moree et al.,1991; Rough et al., 1998). They are being used as anti-microbial (Ozbek et al., 2007), anti-convulsant (Siddiqui et al., 2007), and for the treatment of inflammatory rheumatic and non-rheumatic processes including onsets and traumatologic lesions (Gennarti et al., 1994). In continuation of our structural studies on various sulfonamide derivatives, herein we report the crystal structure of the title compound (I) (Akkurt et al., 2011; Aziz-ur-Rehman, Rafique et al., 2010; Aziz-ur-Rehman, Sajjad et al., 2010; Aziz-ur-Rehman, Siddiqa et al., 2010; Khan, Akkurt et al., 2010; Khan, Sharif et al., 2010).
As shown in Fig. 1, the S atom of the title molecule has a distorted tetrahedral coordination geometry, with S1—O1 = 1.424 (3), S1—O2 = 1.436 (3), S1— N1 = 1.586 (3), S1—C7 = 1.747 (4) Å, O1—S1—O2 = 120.39 (18), O1—S1—N1 = 108.09 (16), O1—S1—C7 = 107.08 (16), O2—S1—N1 = 105.37 (16), O2—S1—C7 = 106.18 (15) and N1— S1—C7 = 109.43 (16)°. The cyclohexane ring (C1–C6) has an almost ideal chair conformation and the ring-puckering parameters (Cremer & Pople, 1975) are QT = 0.559 (4) Å, θ = 1.8 (4) ° and ϕ = 338 (9)°.
In the crystal structure, adjacent molecules form zigzag hydrogen-bonded chains directed along the c axis, linking by intermolecular N—H···O hydrogen bonds (Table 1). The packing and hydrogen bonding of (I) are viewed down a, b and c axes, respectively, in Figs. 2, 3 and 4.
