In the title compound, C20H19ClN4OS, the pyrazole ring makes dihedral angles of 89.2 (4) and 46.4 (4)° with the phenyl and substituted benzene rings, respectively; these two six-membered rings are twisted by 52.1 (4)° with respect to each other. There are intramolecular hydrogen bonds of types N—H⋯O and N—H⋯Cl.

Powdered ammonium thiocyanate (1.14 g, 15 mmol), 5-chloro-3-methyl-1-phenyl-pyrazole-4-carbonyl chloride (2.54 g, 10 mmol), polyethylene glycol-400 (0.5 ml) and acetone (25 ml) were placed in a dried round-bottomed flask containing a magnetic stirrer bar and stirred at room temperature for 1 hr, then 2,6-dimethylbenzenamine (1.15 g, 9.5 mmol) was added, and the mixture was stirred for 5 hr. The mixture was poured into water (20 ml). The resulting solid was filtered, dried and recrystallized from N,N-dimethylformamide-ethanol (1:1, v/v) to yield single crystals of (I) by slow evaporation at room temperature.
The H-atoms bonded to N-atoms were located from difference map and were allowed to refine freely. All other H atoms were positioned geometrically and included in the refinements using a riding model, with C—H = 0.95 and 0.98 Å and Uiso(H) = 1.2 and 1.5 times Ueq(C), respectively, for the aromatic and methyl type H-atoms.
In the structure of the title compound, (I), the pyrazole ring makes dihedral angles of 89.2 (4) and 46.4 (4)°, with the phenyl rings, C2—C7 and C15—C20, respectively, which are twisted by 52.1 (4)° with respect to each other (Fig. 1). However in a similar structure, N-(5-chloro-3-methyl-1-phenyl pyrazole-4-ylcarbonyl)-N' -(4-methphenyl)thiourea (Du et al., 2007), the corresponding phenyl rings from dihedral angles of 74.3 (3) and 2.9 (3)°, respectively, with the central pyrazole system and the dihedral angle between the phenyl rings is 71.6 (3)°. All the bond lengths and angles are in the normal range, corresponding to the related references (Du et al., 2007; Saeed & Flörke, 2007; Wang et al., 2007). The structure is stabilized by N—H···O and N—H···Cl intramolcular hydrogen bonds; details of hydrogen-bonding geometry have been given in the Table.

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. |

In the structure of the title compound, (I), the pyrazole ring makes dihedral angles of 89.2 (4) and 46.4 (4)°, with the phenyl rings, C2—C7 and C15—C20, respectively, which are twisted by 52.1 (4)° with respect to each other (Fig. 1). However in a similar structure, N-(5-chloro-3-methyl-1-phenyl pyrazole-4-ylcarbonyl)-N' -(4-methphenyl)thiourea (Du et al., 2007), the corresponding phenyl rings from dihedral angles of 74.3 (3) and 2.9 (3)°, respectively, with the central pyrazole system and the dihedral angle between the phenyl rings is 71.6 (3)°. All the bond lengths and angles are in the normal range, corresponding to the related references (Du et al., 2007; Saeed & Flörke, 2007; Wang et al., 2007). The structure is stabilized by N—H···O and N—H···Cl intramolcular hydrogen bonds; details of hydrogen-bonding geometry have been given in the Table.
