چکیده
In the mol-ecule of title pyrazoline derivative, C17H18N4OS, the pyrazole ring adopts an envelope conformation with the flap atom, which bears the meth-oxy-phenyl substituent, displaced by 0.0750 (12) Å from the plane through the other ring atoms. The two substituted benzene rings make a dihedral angle of 70.59 (6)°. The meth-oxy group is twisted slightly with respect to the attached benzene ring [Cmeth-yl-O-C-C torsion angle = -8.84 (15)°]. An intra-molecular N-H⋯N hydrogen bond occurs. In the crystal, the pyrazoline mol-ecules are linked by N-H⋯O and N-H⋯S hydrogen bonds into zigzag layers parallel to the bc plane and stacked along the a axis by π-π inter-actions with centroid-centroid distances of 3.4690 (7) and 3.5792 (7) Å. C-H⋯π inter-actions are also present.
