(4-Methyl-phen-yl)[1-(4-methyl-phen-yl)-3-(5-nitro-2-fur-yl)-1H-pyrazol-4-yl]methanone.


ABSTRACT: In the title pyrazole compound, C(22)H(17)N(3)O(4), an intra-molecular C-H?O contact generates a seven-membered ring, producing an S(7) ring motif. The furan and pyrazole rings are essentially planar [maximum deviations = 0.004?(1) and 0.004?(2)?Å, respectively] and are almost coplanar, making a dihedral angle of 3.75?(10)°. One of the methyl-phenyl groups is inclined to the pyrazole ring, as indicated by the dihedral angle of 48.41?(9)°. In the crystal structure, mol-ecules are linked into chains along [10] by C-H?O contacts. The crystal structure is further stabilized by ?-? inter-actions [centroid-centroid distance = 3.4437?(10)?Å].
