In the 22H28N2O6S2, the contains one half molecule with a center of symmetry at the mid-point of the central C—C bond. The conformations of all the N—H, C= O and C—H bonds in the central amide and aliphatic segments are anti to their adjacent bonds. The molecule is bent at the S atom with an C—SO2—NH—C(O) torsion angle of −76.4 (3)°. The dihedral angle between the benzene ring and the SO2—NH—C(O) segment in the two halves of the molecule is 67.2 (1)°. In the crystal, N—H⋯O(C) intermolecular hydrogen bonds link the molecules into chains along the b axis.

N,N-Bis(4-methylphenylsulfonyl)-suberamide was prepared by refluxing a mixture of suberic acid (0.01 mol) with 4-methylbenzenesulfonamide (0.02 mol) and POCl3 (0.02 mol) for 1 h on a water bath. The reaction mixture was allowed to cool and added ether to it. The solid product obtained was filtered, washed thoroughly with ether and hot ethanol. The compound was recrystallized to the constant melting point and was characterized by its infrared and NMR spectra.
Plate like colorless single crystals used in the X-ray diffraction studies were grown by a slow evaporation of a solution of the compound in ethanol at room temperature.
The H atom of the NH group was located in a difference map and later restrained to the distance N—H = 0.86 (2) Å. The other H atoms were positioned with idealized geometry using a riding model with the aromatic C—H = 0.93 Å, the methyl C—H = 0.96Å and the methylene C—H = 0.97 Å. All H atoms were refined with isotropic displacement parameters. The Uiso(H) values were set at 1.2Ueq(C-aromatic, N) and 1.5Ueq(C-methyl).

Geometry. All e.s.d.'s (except the e.s.d. in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell e.s.d.'s are taken into account individually in the estimation of e.s.d.'s in distances, angles and torsion angles; correlations between e.s.d.'s in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell e.s.d.'s is used for estimating e.s.d.'s involving l.s. planes. |
Refinement. Refinement of F2 against ALL reflections. The weighted R-factor wR and goodness of fit S are based on F2, conventional R-factors R are based on F, with F set to zero for negative F2. The threshold expression of F2 > σ(F2) is used only for calculating R-factors(gt) 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. |

The amide and sulfonamide moieties are important constituents of many biologically significant compounds. As part of our studies on the effects of ring and side chain substitutions on the structures and other aspects of N-(aryl)-amides (Arjunan et al., 2004; Gowda et al., 1999, 2006), N-(aryl)-methanesulfonamides (Gowda et al., 2007) and N-(arylsulfonyl)-amides (Rodrigues et al., 2011), the crystal structure of N,N-bis(4-methylphenylsulfonyl)-suberamide (I) has been determined (Fig. 1).
In the two C—SO2—NH—CO—CH2—CH2—CH2— central segments of the structure, all the N—H, C=O and C—H bonds in the amide and aliphatic segments are anti to the adjacent bonds, similar to that observed in N,N-bis(4-chlorophenylsulfonyl)-suberamide (II) (Rodrigues et al., 2011). The orientations of sulfonamide groups with respect to the attached phenyl rings are given by the C2—C1—S1—N1 and C6—C1—S1—N1 torsion angles of 78.2 (4)° and -104.3 (3)°, respectively, compared to the corresponding angles of 67.2 (3)° and -113.9 (4)° in (II).
The molecule is bent at the S atom with the C1—S1—N1—C7 torsion angle of -76.4 (3)°, compared to the value of -80.6 (4)° in (II). In (I), the aliphatic chain is almost linear with C7—C8—C9—C10 torsion angle of -176.9 (3)°, compared to the value of -179.4 (4)° in (II).
The dihedral angle between the benzene ring and the SO2—NH—C(O) segment in the two halves of the molecule is 67.2 (1)°, compared to the value of 79.5 (2)° in (II).
The structure shows simultaneous of N—H···O(C) and N—H···O(S) intermolecular hydrogen bonds (Table 1), which link the molecules into infinite chains along the b-axis.
