چکیده
The asymmetric unit of the title compound, C16H11BrN2O, contains two independent mol-ecules with slightly different geometries. The 4-bromo-benzene ring forms dihedral angles of 26.0 (2) and 39.9 (7)° with the pyrazole ring in the two mol-ecules while the phenyl ring is oriented at 19.7 (5) and 7.3 (0)° with respect to the pyrazole ring.

In the title compound, C(16)H(11)BrN(2)O, the phenyl and chloro-benzene rings are twisted out of the mean plane of the pyrazole ring, forming dihedral angles of 13.70 (10) and 36.48 (10)°, respectively. The carbaldehyde group is also twisted out of the pyrazole plane [the C-C-C-O torsion angle is 7.9 (3)°]. A helical supra-molecular chain along the b axis and mediated by C-H⋯O inter-actions is ...
