The title compound, C₁₉H₁₉N₃O₂, crystallizes with two independent molecules (A and B) in the asymmetric unit. In molecule A, the pyrazole ring adopts a slightly disordered half-chair conformation while in B it is planar [r.m.s. deviation = 0.0386 (15) Å]. The dihedral angle between the mean planes of the two phenyl rings is 56.2 (8) in A and 38.2 (3)° in B. The N-phenyl substituent on the pyrazole ring is twisted by 46.5 (2) in A and 58.6 (4)° in B while the extended phenyl ring is twisted by 82.2 (8) in A and 87.5 (9)° in B. The mean plane of the amide group forms an angle of 74.8 (3) in A and 67.7 (1)° in B with respect to the phenyl ring. In addition, the amide group is rotated by 51.4 (1) in A and 53.6 (2)° in B from the the mean plane of the pyrazole ring. In the crystal, the two molecules are linked via N—H⋯O hydrogen bonds, supported by weak C—H⋯O interactions, forming dimers enclosing an R₂²(10) ring motif. The dimers are linked via C—H⋯O interactions, forming a three-dimensional structure.

Comment top

N-Substituted 2-arylacetamides are biologically active compounds because of their structural similarity to the lateral chain of natural benzylpenicillin (Mijin et al., 2008). Amides are also used as ligands due to their excellent coordination abilities (Wu et al., 2008, 2010). In a variety of biological heterocyclic compounds, N-pyrazole derivatives are of great interest because of their chemical and pharmaceutical properties (Cheng et al., 2008). Some of the N-pyrazole derivatives have been found to exhibit good insecticidal activities (Hatton et al., 1993), antifungal activities (Liu et al., 2010) and non-linear optical properties (Chandrakantha et al., 2013). Crystal structures of some related acetamide and pyrazole derivatives are : N-(4-Bromophenyl)-2-(naphthalen-1-yl) acetamide, N-(3,5-Dichlorophenyl)-2-(naphthalen-1-yl)acetamide, N-(1,5-Dimethyl-3-oxo-2-phenyl-2,3-dihydro-1H-pyrazol-4-yl)-2- [4-(methylsulfanyl)phenyl]acetamide, (Fun et al., 2011a,b, 2012), 2-(2,4-Dichlorophenyl)-N-(1,5-dimethyl-3-oxo-2- phenyl-2,3-dihydro-1H-pyrazol-4-yl)acetamide, 2-(2,6-dichloro phenyl)-N-(1,5-dimethyl-3-oxo-2-phenyl-2,3-dihydro-1H-pyrazol- 4-yl)acetamide (Butcher et al., 2013a,b) have been reported. In view of the importance of amide derivatives of pyrazoles, this paper reports the crystal structure of the title compound (I), C₁₉H₁₉N₃O₂.

The title compound, (I), crystallizes with two independent molecules in the asymmetric unit (A and B) (Fig. 1). In molecule A, the pyrazole ring adopts a slightly disordered half-chair conformation while in B it is planar. The dihedral angle between the mean planes of the two phenyl rings is 56.2 (8)° (A) and 38.2 (3)° (B). The N-phenyl substituent on the pyrazole ring is twisted by 46.5 (2)° (A) and 58.6 (4)° (B) while the extended phenyl ring is twisted by 82.2 (8)° (A) and 87.5 (9)° (B). The mean plane of the amide group forms an angle of 74.8 (3)° (A)(C2A/C1A/O1A/N1A), 67.7 (1)° (B)(C2B/C1B/O1B/N1B) with respect to that of the phenyl rings. In addition, the amide group is rotated by 51.4 (1)° (A), 53.6 (2)° (B) from the the mean plane of the pyrazole rings. Bond lengths are in normal ranges (Allen et al., 1987). N—H···O intermolecular hydrogen bonds supported by a weak C14A—H14A···O1A intermolecular interaction are observed which link the molecules into dimers forming R₂²(10) graph set motifs (Fig. 2). Also, additional weak C—H···O intermolecular interactions are also observed which interlink the dimers and influence the crystal packing.

Experimental top

Phenylacetic acid (0.136 g, 1 mmol) and 4-aminoantipyrine (0.203 g, 1 mmol), 1-ethyl-3-(3-dimethylaminopropyl)-carbodiimide hydrochloride (1.0 g, 0.01 mol) and were dissolved in dichloromethane (20 mL). The mixture was stirred in presence of triethylamine at 273 K for about 3 h. The contents were poured into 100 ml of ice-cold aqueous hydrochloric acid with stirring, which was extracted thrice with dichloromethane. Organic layer was washed with saturated NaHCO₃ solution and brine solution, dried and concentrated under reduced pressure to give the title compound (I). Single crystals were grown from methanol and acetone mixture (1:1) and further recrystallised from ethanol by by the slow evaporation method which were used as such for X-ray studies (M.P.: 445-447 K).

Special details top

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.
