Abstract

The title compound, C(13)H(13)F(3)N(2)O(2), crystallizes with two independent mol-ecules in the asymmetric unit, with different conformations of their ethyl side chains. The dihedral angles formed between the 1H-pyrazole and benzene rings in the two mol-ecules are 79.44 (6) and 77.81 (6)°. In the crystal, mol-ecules are linked by O⋯H-N hydrogen bonds into chains propagating along [001] and the packing is further stabilized by π-π inter-actions [centroid-centroid separations = 3.5409 (10) and 3.6335 (10) Å].
