摘要： There are two molecules in the asymmetric unit of the title compound, C(12)H(9)BrF(2)N(2)O. They have very similar conformations: the dihedral angles between their pyrazole and benzene ring systems are 78.4 (3) and 78.6 (4)degrees. In the crystal, weak aromatic pi-pi stacking [centroid-centroid separation = 3.696 (5) angstrom] helps to establish the packing.
