N,N′-Bis(phenyl­sulfon­yl)succinamide

In the crystal structure of the title compound, C₁₆H₁₆N₂O₆S₂, the conformation of the N—C bonds in the C—SO₂—NH—C(O)—C segments have gauche torsions with respect to the S=O bonds, while the conformations of the N—H and C=O bonds in the amide fragments are trans to each other and the amide O atom is anti to the H atoms attached to the adjacent C atom. The mol­ecule is bent at the S atom with a C—SO₂—NH—C(O) torsion angle of 65.2 (2)°. The molecule lies about a centre of inversion. The dihedral angle between the benzene ring and the SO₂—NH—C(O)—C₂ segment in the two halves of the mol­ecule is 77.4 (1)°. The structure exhibits both intra­molecular and inter­molecular hydrogen bonds. A series of N—H⋯O(S) hydrogen bonds links the mol­ecules into infinite chains.

S1. Comment

Diaryl acylsulfonamides are known as potent antitumor agents against a broad spectrum of human tumor xenografts in nude mice. As part of a study of the effect of ring and the side chain substituents on the solid state structures of N-aromatic sulfonamides (Gowda et al., 2009a,b; Suchetan et al., 2009), in the present work, the structure of N,N-(diphenylsulfonyl)succinamide has been determined (Fig.1).

The conformation of the N—C bonds in both the C—SO₂—NH—C(O)—C segments have gauche torsions with respect to the S═O bonds, while the conformations of N—H and C=O bonds in the amide fragments are trans to each other and the amide O atoms are anti to the H atoms attached to the adjacent C atoms. The molecule is bent at the S atoms with the C—SO₂—NH—C(O) torsion angle of 65.2 (2)°. The dihedral angle between the benzene ring and the SO₂—NH—C(O)—C₂ segment in the two halves of the molecule is 77.4 (1)°. The structure exhibits both the intramolecular and intermolecular hydrogen bonds. The series of N—H···O(S) hydrogen bonds (Table 1) link the molecules into infinite chains (Fig. 2).

S2. Experimental

N,N-(Diphenylsulfonyl)succinamide was prepared by refluxing a mixture of succinic anhydride (0.01 mol) with benzenesulfonamide (0.02 mol) and POCl3 for 1 hr 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 alcohol. The compound was recrystallized to the constant melting point (235–237° C).

Rod like single crystals used in the X-ray diffraction studies were obtained from a slow evaporation of a solution of the compound in methyl ethyl ketone at room temperature.

S3. Refinement

The H atom of the NH group was located in difference map and later restrained to N—H = 0.86 (2) Å. The other H atoms were positioned with idealized geometry using a riding model [C—H = 0.93—0.97 Å]. All H atoms were refined with isotropic displacement parameters (set to 1.2 times of the U_eq of the parent atom).

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.
