The title compound, C25H22N2O4S, features a tetra-substituted pyrazole ring. The dihedral angles formed between the five-membered ring (r.m.s. deviation = 0.007 Å) and the N- and C-bound phenyl rings are 48.10 (7) and 72.01 (7) °, respectively, indicating that the planes through the residues are significantly twisted from the plane through the heterocycle. The ester-CO2 group is also twisted out of this plane, with an O—C—C—N torsion angle of −29.04 (11)°. The sulfonyl-O atoms lie to one side of the pyrazole plane and the sulfonylphenyl ring to the other. The dihedral angle between the two ring planes is 70.63 (7) °. Supramolecular arrays are formed in the sustained by C—H⋯O and C—H⋯π(pyrazole) interactions and methyl-C—H⋯π(N-bound benzene) contacts.

1-Phenyl-2-(phenylsulfonyl)ethanone (0.26 g, 1 mmol) was added to a stirred ethanolic sodium ethoxide solution [prepared from sodium metal (0.023 g, 1 mmol) and 25 ml of absolute ethanol]. After stirring for 20 min, ethyl 2-chloro-2-(2-p-tolylhydrazono)acetate (0.241 g, 1 mmol) was added and the reaction mixture was left to stir at room temperature for 12 h. Cold water (50 ml) was then added. The solid product was collected by filtration, washed with water and dried. Recrystallization from ethanol afforded the title pyrazole. The yellow blocks were isolated from its ethanol solution by slow evaporation at room temperature
H-atoms were placed in calculated positions [C—H 0.95 to 0.99 Å, Uiso(H) 1.2 to 1.5Ueq(C)] and were included in the
in the riding model approximation.Our previous work evaluating the biological potential of pyrazole derivatives (Abdel-Wahab et al., 2009; Abdel-Aziz et al., 2009; Abdel-Aziz et al., 2010) lead to the characterization of the title compound, (I).
The molecular structure of (I), Fig. 1, features a tetra-substituted pyrazole ring. The ester group is twisted out of the plane through the five-membered ring (r.m.s. deviation = 0.007 Å) as seen in the value of the O3—C3—C4—N1 torsion angle of -29.04 (11) °. The ring-connected benzene rings, (C13–C18) and (19–C24), form dihedral angles of 72.01 (7) and 48.10 (7) °, respectively, with the pyrazole ring also indicating significant twists; the dihedral angle between the two ring-bound benzene rings is 71.93 (7) °. With respect to the least-squares plane through the pyrazole ring, the sulfonyl-O atoms lie to one side, and the benzene ring to the other; the dihedral angle between the pyrazole and sulfonyl-benzene rings is 70.63 (7) °, indicating an almost orthogonal relationship.

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. |

Our previous work evaluating the biological potential of pyrazole derivatives (Abdel-Wahab et al., 2009; Abdel-Aziz et al., 2009; Abdel-Aziz et al., 2010) lead to the characterization of the title compound, (I).
The molecular structure of (I), Fig. 1, features a tetra-substituted pyrazole ring. The ester group is twisted out of the plane through the five-membered ring (r.m.s. deviation = 0.007 Å) as seen in the value of the O3—C3—C4—N1 torsion angle of -29.04 (11) °. The ring-connected benzene rings, (C13–C18) and (19–C24), form dihedral angles of 72.01 (7) and 48.10 (7) °, respectively, with the pyrazole ring also indicating significant twists; the dihedral angle between the two ring-bound benzene rings is 71.93 (7) °. With respect to the least-squares plane through the pyrazole ring, the sulfonyl-O atoms lie to one side, and the benzene ring to the other; the dihedral angle between the pyrazole and sulfonyl-benzene rings is 70.63 (7) °, indicating an almost orthogonal relationship.
The crystal structure features supramolecular arrays in the ac plane sustained by C—H···O and C—H···π interactions [involving the pyrazole ring as the acceptor], Fig. 2 and Table 1. Layers are connected along the b direction by C—H···.π interactions involving methyl-H and the N-bound benzene ring, Fig. 3 and Table 1.
