The syntheses and crystal structures of the isomeric 4-bromo-N-[(2-nitrophenyl)sulfonyl]benzamide, (I), and 4-bromo-N-[(4-nitrophenyl)sulfonyl]benzamide, (II), are described (molecular formula = C13H9BrN2O5S in each case). The of (I) contains two independent molecules [(IA) and (IB)], while that of (II) contains one molecule. The benzoic acid aromatic ring of molecule (IA) is disordered due to rotation about the Car—C(=O) bond over two orientations in a 0.525 (9):0.475 (9) ratio. The dihedral angle between the benzene rings is 85.9 (3)° in (IA) and 65.22 (19)° in (IB), while in (II), the corresponding value is 56.7 (7)°. In the crystals of (I) and (II), N—H⋯O, C—H⋯O and C—H⋯π interactions generate three-dimensional networks.
1. Chemical context
In recent years, N-(arylsulfonyl)arylamides have received much attention as they constitute an important class of drugs for treating Alzheimer's disease (Hasegawa & Yamamoto, 2000) and acting as anti-bacterial inhibitors of synthetases (Banwell et al., 2000), antagonists for angiotensin II (Chang et al., 1994) and as leukotriene D4-receptors (Musser et al., 1990). Further, N-(arylsulfonyl)-arylamides are known to be potent anti-tumour agents against a broad spectrum of human tumour xenografts (colon, lung, breast, ovary and prostate) in mice (Mader et al., 2005). In a continuation of our work on the synthesis and crystal structures of N-(2-nitrophenylsulfonyl)arylamides (Suchetan et al., 2012a) and N-(4-nitrophenylsulfonyl)arylamides (Suchetan et al., 2012b), compounds (I) and (II) were synthesized and their crystal structures determined.
2. Structural commentary
The (Fig. 1) contains two independent molecules, (IA) and (IB), while that of (II) contains one molecule (Fig. 2). In both molecules (IA) and (IB), the ortho-nitro substitution on the benzenesulfonyl ring is syn to the N—H bond in the central –C—SO2—N—C(O)– segment (Fig. 1). The benzoic acid ring of molecule (IA) is disordered due to rotation about the Car—C(=O) bond over two orientations in a 0.525 (9):0.475 (9) ratio, which are inclined to each other by 45.5 (4)°. The nitro groups in both the A and B molecules of (I) and the molecule of (II) are twisted relative to the attached benzenesulfonyl rings: the torsion angle C1—C2—N2—O4 in (IA) is 56.3 (4)°, while in (IB), the torsion angle C14—C15—N4—O9 is 35.6 (5)°, whereas in (II), the C5—C4—N2—O4 torsion angle has a value of 19.4 (5)°. The dihedral angle between the benzene rings is 85.9 (3)° in (IA), 65.22 (19)° in (IB) and 56.7 (7)° in (II). The conformation of (II) is supported by an intramolecular C2—H2⋯O3 interaction (Table 2), forming an S(7) motif.
of (I)3. Supramolecular features
The features two N—H⋯O hydrogen bonds, namely N1—HN1⋯O6 and N3—HN3⋯O4 (Table 1) between the A and B molecules, resulting in a hetero dimer with graph-set motif R22(11), which is consolidated by a C13—H13A⋯O6 interaction between the A and B molecules (Fig. 3). The A + B dimers assemble along the a-axis direction via C23—H23⋯O8 interactions, forming C6 chains (Table 1, Fig. 3). A dimeric R12(5) network generated by the C25—H25⋯O3 and C26—H26⋯O3 interactions (Table 1, Fig. 3) and the R22(11) network, which alternate along the c-axis direction, build a network of C22(14) and C22(15) chains as part of a zigzag sheet propagating in the ac plane, which features a short Br2⋯O3 contact [3.212 (2) Å]. Further, C10—H10B⋯π1 [where π1 is the nitrobenzene ring of molecule (IB)] and C12—H12A⋯π2 [π2 is the bromobenzene ring of molecule (IA)] extend the zigzag sheets into a three-dimensional architecture, which is consolidated by several aromatic π–π stacking interactions [centroid–centroid separations = 3.873 (4), 3.785 (5) and 3.698 (5) Å].
of (I)
|
The features N1—HN1⋯O3 hydrogen bonds forming C(4) chains along [100] (Table 2, Fig. 4): these chains are further strengthened by C13—H13⋯O3 interactions (Table 2) forming C(5) chains. The molecules of neighbouring chains are interlinked via C3—H3⋯O4 and C12—H12⋯O4 interactions (i.e. O4 acts as a double acceptor) and thus, a zigzag sheet propagates in the ac plane (Table 2). The C12—H12⋯O4 and C3—H3⋯O4 interactions run as C(13) and C(5) chains, respectively, along [001]. Molecules in adjacent layers are linked via C9—H9⋯O2 and C10—H10⋯O1 interactions that form C(7) and C(8) chains propagating along the b-axis direction, and thus a three-dimensional network is obtained. A short O5⋯Br1 [3.173 (4) Å] contact is observed.
of (II)4. Database survey
A survey of the Cambridge Structural Database (Groom et al., 2016) revealed 82 phenylsulfonyl-arylamide structures with different substituents attached to the benzene rings including the parent compound N-benzoylbenzenesulfonamide (Gowda et al., 2009).
5. Synthesis and crystallization
Compounds (I) and (II) were prepared by refluxing a mixture of 4-bromobenzoic acid, the corresponding substituted benzenesulfonamide and phosphorus oxychloride for 3 h on a water bath. The resultant mixtures were cooled and poured into ice-cold water. The solids obtained were filtered, washed thoroughly with water and then dissolved in sodium bicarbonate solutions. The compounds were later reprecipitated by acidifying the filtered solutions with dilute HCl. They were filtered, dried and recrystallized. [m.p. = 486 for (I) and 498 K for (II)]. Colourless prisms of (I) and (II) were obtained by slow evaporation of the respective solutions of the compounds in methanol (with a few added drops of water).
6. details
Crystal data, data collection and structure . The H atoms of the NH groups in (I) and (II) were located in a difference map and later refined freely. The carbon-bound H atoms were positioned with idealized geometry and refined using a riding model with C—H = 0.95 Å, and with Uiso = 1.2Ueq(parent atom).

Geometry. All esds (except the esd in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell esds are taken into account individually in the estimation of esds in distances, angles and torsion angles; correlations between esds in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell esds is used for estimating esds involving l.s. planes. |

Geometry. All esds (except the esd in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell esds are taken into account individually in the estimation of esds in distances, angles and torsion angles; correlations between esds in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell esds is used for estimating esds involving l.s. planes. |
