N-(5-Chloro-3-methyl-1-phenylpyrazol-4-ylcarbonyl)-N'-(2-methoxyphenyl)thiourea

H. Du, H. Du, M. Lu and L. Sun

Abstract top

In the title compound, C19H17ClN4O2S, the dihedral angle between the pyrazole and phenyl rings is 43.3 (3)°. The bridging unit between the pyrazole and methoxyphenyl rings is planar within 0.0169 Å and makes dihedral angles of 2.3 and 26.4°, respectively, with these two rings. This conformation is influenced by intramolecular N-H...O and N-H...Cl hydrogen bonds. The crystal packing is stabilized by C-H...[pi] interactions.

Comment top

The molecular structure of (I) with the atom-numbering scheme is shown in Fig.1. The pyrazole ring makes dihedral angles of 43.3° and 24.5°, with C1—C6 and C13—C18 rings, respectively; these two six-membered rings are twisted by 19.6° with respect to each other. However, in the similar structure, N-(5-chloro-3-methyl-1-phenyl pyrazole-4-ylcarbonyl)-N'-(4-methphenyl)thiourea (Du et al., 2007), the two phenyl rings deviate from the central pyrazole system with dihedral angles of 74.3° and 2.9°, respectively, the dihedral angle between them being 71.6°. 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). There also exist two intramolecular N—H···O and N—H···Cl hydrogen bonds and two C—H···pi interaction (Table 1.). Investigation on the packing pattern demonstrates that those discrete molecules are interconnected by slightly weak contacts C2—H2···Cg1 and C10—H10B···Cg2 [Cg1=C1—C6 and Cg2=C13—C18] into a two-dimensional network, as shown in Fig. 2.

Experimental top

Powdered ammonium thiocyanate (15 mmol), 5-chloro-3-methyl-1-phenyl-pyrazole-4-carbonyl chloride (10 mmol), PEG-400 (0.15 mmol) and acetone (25 mL) were placed in a dried round-bottomed flask containing a magnetic stirrer bar and stirred at room temperature for 1 h. Then 2-methoxybenzenamine (9.5 mmol) was added, and the mixture was stirred for 5 h. The mixture was poured into water (20 mL). The resulting solid was filtered, dried and recrystallized from DMF-EtOH to give N-(5-chloro-3-methyl-1-phenyl pyrazole-4-ylcarbonyl)-N'-(2-methoxyphenyl)thiourea. Single crystals of the title compound were obtained by slow evaporation of a solution in DMF-EtOH(1:1,v/v).

Refinement top

H atoms bonded to N atoms were located in a difference map and refined with distance restraint of N—H = 0.89 Å with Uiso(H) = 1.2Ueq(N). Other H atoms were positioned geometrically and refined using a riding model, with C—H = 0.93–0.96 Å and with Uiso(H) = 1.2 (1.5 for methyl groups) times Ueq(C).

Special details top

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.
