N,N-(Diphenylsulfonyl)maleamide was prepared by refluxing a mixture of maleic anhydride (0.01 mol), benzenesulfonamide (0.02 mol) and POCl3 for 3hr on a water bath. The reaction mixture was allowed to cool. Ether was added to it. The solid product obtained was filtered off, washed thoroughly with ether and hot alcohol and recrystallized to the constant melting point of 255–259° C
Rod like single crystals used in the X-ray diffraction studies were obtained from a solution of the compound in DMF.
The H atom of the NH group was located in difference map and later restrained to N—H = 0.86 (1) Å. The other H atoms were positioned with idealized geometry using a riding model with C—H = 0.93 Å. All H atoms were refined with isotropic displacement parameters set to 1.2 times of the Ueq 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. |

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., 2009, 2010; Suchetan et al., 2009), in the present work, the structure of N,N-(Diphenylsulfonyl)maleamide (I) has been determined (Fig. 1).
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, similar to that observed in N,N-(diphenylsulfonyl)succinamide (II)(Gowda et al., 2010). The molecule is bent at the S atoms with the C—SO2—NH—C(O) torsion angle of 66.1 (2)° in (II), compared to the value of 65.2 (2)°. The dihedral angle between the benzene ring and the SO2—NH—C(O)—C segment in the two halves of the molecule is 76.4 (1)°, compared to the corresponding angle of 77.4 (1)° in (II). 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 column like infinite chains parallel to a-axis (Fig. 2).
