چکیده
In the title mol-ecule, C(24)H(15)BrCl(2)N(2)O, the dihedral angles betwen the pyrazole ring and its N-bonded phenyl (A) and C-bonded bromo-benzene (B) rings are 10.34 (16) and 40.95 (15)°, respectively. The dihedral angle between rings A and B is 56.89 (17)°. The title mol-ecule exists in a trans conformation with respect to the acyclic C=C bond. In the crystal, mol-ecules are linked into inversion dimers by pairs of C-H⋯O hydrogen bonds, generating R(2) (2)(14) loops. The crystal structure is further consolidated by C-H⋯π inter-actions.
