In the title compound, C29H34N2S2, the pyrazole ring is planar and both cyclohexane rings adopt chair conformations. The dihedral angles between the pyrazole ring and the two benzene rings are 59.9 (2) and 19.8 (2)°. The conformation and packing of the molecules in the are stabilized by a weak intramolecular C—H⋯S and C—H⋯N interactions, in addition to van der Waals forces.

A mixture of 2-(cyclohexylsulfanyl)-1-phenyl-1-ethanone N-[(E)-2- (cyclohexylsulfanyl)-1-phenylethylidene]hydrazone (0.003 mole) and 3 ml of dimethyl formamide were kept in an ice bath at 273 K and phosphorus oxychloride (0.024 mole) was added dropwise for 5 to 10 minutes. The reaction mixture was then kept in a microwave oven at 600 W for 30–60 sec. The process of the reaction was monitored by TLC. After completion of the reaction, the reaction mixture was poured into crushed ice and extracted with dichloromethane. The organic layer was dried with anhydrous sodium sulfate. The different compounds present in the mixture were separated by
using petroleum ether and ethyl acetate as the (99:1 v/v, Rf index of the title compound: 0.8336). The isolated title compound was recrystallized from dichloromethane to obtain 4-(cyclohexylsulfanyl) -1-[(E)-2-(cyclohexylsulfanyl)-1-phenylethenyl]-3 -phenyl-1H -pyrazole (title compound) and 4-(cyclohexyl sulfanyl)-1-[Z-2 -(cyclohexylsulfanyl)-1-phenyl-1-ethenyl]-3-phenyl-1H-pyrazole in 38% and 60% yield. The compounds identified through column are characterized by NMR studies (Manikannan, 2008).H atoms were positioned geometrically (C—H = 0.93–0.98 Å) and allowed to ride on their parent atoms, with Uiso(H) = 1.2Ueq(C) for all H atoms.

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. |

Pyrazole derivatives possess significant antiarrhythmic and sedative (Bruno et al., 1990), hypoglycemic (Cottineau et al., 2002), antiviral (Baraldi et al., 1998), and pesticidal (Londershausen, 1996) properties. Some pyrazole derivatives were successfully tested for their antifungal (Chen & Li, 1998), antihistaminic (Mishra et al., 1998) and anti-inflammatory (Smith et al., 2001) properties.
An ORTEP plot of the molecule is shown in Fig. 1 and a packing plot in Fig. 2. The pyrazole ring adopts a planar conformation. The sum of the angles at N1 of the pyrazole ring (359.95°) is in accordance with sp2 hybridization (Beddoes et al., 1986). Both the cyclohexane rings in the molecule adopt chair conformations which can be seen from the puckering (Cremer & Pople, 1975) and the asymmetry parameters (Nardelli, 1983). The values for the ring C8-C13 are: q2 = 0.010 (4) Å, q3 = - 0.562 (4) Å, π = 186 (22)°, Δs(C9) and Δs(C12) =0.5 (4)° and for ring C20-C25 are: q2 = 0.014 (4) Å, q3 = - 0.572 (4) Å, π = 132 (14)°, Δs(C22) and Δs(C25) = 0.3 (3)°.
The best least-squares planes calculated for the two cyclohexane rings (atoms C8, C9, C11 & C12 lie in the plane and C10 & C13 deviate for one of the rings; atoms C21, C22, C24 & C25 lie in the plane and C20 & C23 deviate for the other ring ) are twisted from the pyrazole ring by 50.06 (17)° and 69.71 (15), respectively. The crystal packing is augmented by weak intramolecular C—H···N and C—H···S interactions in addition to van der Waals forces.
