(4-Bromo-3,5-dimethyl-1H-pyrazol-1-yl)(2,6-difluorophenyl)methanone
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)°. In the crystal, weak aromatic π–π stacking [centroid–centroid separation...
