In the title compound, C25H20N2O5S, the benzodioxole ring system is essentially planar [maximum deviation = 0.021 (2) Å] and forms dihedral angles of 85.2 (1) and 74.2 (1)°, respectively, with the formyl benzene and sulfonyl-bound benzene rings. In the crystal, C—H⋯O hydrogen bonds generate C(8) chains along [100] and R33(19) ring motifs. In addition, a weak π–π interaction [centroid–centroid distance = 3.937 (3) Å] is also observed.

To a stirred solution of N-(2-formylphenyl)-4-methylbenzenesulfonamide (0.275 g, 1 mmol) in acetonitrile (7 ml), potassium carbonate (0.35 g, 2.5 mmol) was added and stirred well for five minutes. To this solution, (z)-methyl 3-(benzo[d][1,3]dioxol-5-yl)-2- (bromomethyl)prop-2-enenitrile (0.299 g, 1 mmol) in acetonitrile (0.5 ml) was added and allowed to stir well for 6 h. After the completion of the reaction, the reaction mixture was poured into water and extracted using ethyl acetate. The organic layer thus obtained was concentrated under reduced pressure and the residual mass thus obtained was purified by
on silica gel (100–200 mesh) using ethylacetate and hexanes (1:9) as solvents. The pure title compound was obtained as a colourless solid (0.435 g, 94% yield). Recrystallization was carried out using ethylacetate as solvent.All the H atoms were positioned geometrically with C–H = 0.93–0.97 Å and constrained to ride on their parent atom, with Uiso(H) =1.5Ueq for methyl H atoms and 1.2Ueq(C) for other H atoms.

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. |
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 > 2sigma(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. |

Sulfonamide drugs are widely used for the treatment of certain infections caused by Gram-positive and Gram-negative microorganisms, some fungi, and certain protozoa (Korolkovas, 1988, Mandell & Sande, 1992). Benzodioxoles derivatives can be used as inhibitors of mono-oxygenase enzymes (Ullrich et al., 2004), pesticides or pesticide intermediates (Gates & Gillon, 1974), herbicides (Arndt & Franke, 1977), antioxidants (Joshi et al., 2005), antimicrobials (Jae et al., 2001) and medicines (Leite et al., 2004). In view of this biological importance, the crystal structure of the title compound has been determined and the results are presented here.
Fig. 1. shows a displacement ellipsoid plot of the title compound, with the atom numbering scheme. The S1 atom shows a distorted tetrahedral geometry, with O2—S1—O3[119.9 (1)°] and N1—S1—C8[107.0 (1)°] angles deviating from ideal tetrahedral values, are attributed to the Thrope-Ingold effect (Bassindale, 1984). The sum of bond angles around N1 (351°) indicates that N1 is in sp2 hybridization. The benzodioxole ring system is essentially planar [maximum deviation = 0.021 (2) Å for the O5 atom] and forms dihedral angles of 85.2 (1)° and 74.2 (1)°, respectively, with the formyl benzene and sulfonyl–bound benzene rings. The carbonitrile side chain (C16–C24–N2) is almost linear, with the angle around central carbon atom being 177.1 (2)°. The geometric parameters of the title molecule agree well with those reported for similar structures (Madhanraj et al., 2011; Aziz-ur-Rehman et al., 2010).
The molecular structure is stabilized by an C15—H15B···O3 intramolecular hydrogen bond, forming an S(5) ring motif (Bernstein et al., 1995) (Table 1). The crystal packing is stabilized by intermolecular C—H···O hydrogen bonds. The formation of the framework can be explained in terms of two-one substructures. In the first substructure, atom C4 in the molecule at (x, y, z) acts as a hydrogen bond donor to atom O3 in the molecule at (-1+x, y, z) generating C(8) chains which are running along [100] (Fig. 2). In the second substructure, three molecules are linked by the combination of C15—H15B···O2 and C23—H23···O1 intermolecular hydrogen bonds generating R33(19) ring motifs along [010] (Fig. 3). The crystal packing (Fig. 4) is further stabilized by weak C—H···π interactions between a dioxole H atom and the benzene ring (C1–C6) of a neighbouring molecule, with a C25—H25A···Cg1iv distance of 3.446 (4) Å (Table 1; Cg1 is the centroid of the C1–C6 benzene ring, Symmetry code: iv = 2-x, -y, 1-z). Additional stability arises from weak aromatic π—π interaction between the benzene rings of neighbouring molecules, with Cg2—Cg2iv distance of 3.937 (3) Å (Fig. 4; Cg2 is the centroid of the C18—C23 benzene ring, symmetry code: iv = 2-x, -y, 1-z).
