چکیده
The mol-ecule of the title pyrazole derivative, C(18)H(19)BrN(4)S, is twisted. The central pyrazole ring, which adopts a flattened envelope conformation, is almost coplanar with the 4-bromo-phenyl ring, whereas it is inclined to the 4-(dimethyl-amino)-phenyl ring making dihedral angles of 1.68 (6) and 85.12 (6)°, respectively. The dihedral angle between the two benzene rings is 86.56 (6)°. The dimethyl-amino group is slightly twisted from the attached benzene ring [C-C-N-C torsion angles = 8.4 (2) and 8.9 (2)°]. In the crystal, mol-ecules are linked by inter-molecular N-H⋯S hydrogen bonds into chains along [20]. The crystal is further stabilized by C-H⋯π inter-actions.
