Abstract

In the title compound, C\sb 21H\sb 16Br\sb 2N\sb 2, the central pyrazole ring adopts an flattened envelope conformation, with the stereogenic C atom in the flap position. The deviations from planarity for this ring are relatively minor (r.m.s. deviation = 0.045Å) and the dihedral angles formed with the N- and C\sb imine-bound benzene rings are 7.73(13) and 11.00(13)\circ, respectively. By contrast, the benzene ring bound at the chiral C atom is almost orthogonal to the rest of the mol\-ecule; the dihedral angle formed between this ring and the pyrazole ring is 79.53(13)\circ. In the crystal, the packing is stabilized by C—-H⋅sN and C—-H⋅sBr inter\-actions.
