摘要：
In the title compound, C16H11BrN2O, the phenyl and chlorobenzene rings are twisted out of the mean plane of the pyrazole ring, forming dihedral angles of 13.70 (10) and 36.48 (10)degrees, respectively. The carbaldehyde group is also twisted out of the pyrazole plane [the C-C-C-O torsion angle is 7.9 (3)degrees]. A helical supramolecular chain along the b axis and mediated by C-H center dot center dot center dot O interactions is the most prominent feature of the crystal packing.
