The title compound, C15H16N2S, was prepared by the reaction of 3,5-dimethylphenylamine with 1-isothiocyanatobenzene. In the molecule, all bond lengths and angles are within normal ranges. The dihedral angle between the two aromatic rings is 48.77 (1)°. The crystal packing is stabilized by van der Waals forces. [ABSTRACT FROM AUTHOR]

In the title structure, C21H16BrClN2, the pyrazoline ring is approximately coplanar with the N-substituted phenyl ring. The dihedral angles formed by the pyrazoline ring with the 4-chloro­phenyl and 4-bromo­phenyl rings are 78.82 and 10.9°, respectively. [ABSTRACT FROM AUTHOR]

The title compound, C11H10N6S, was prepared by the reaction of ethyl 2-(1 H-1,2,4-triazol-1-yl)­acetate with hydrazine and phenyl iso­thio­cyanate. The molecular structure and packing are stabilized by an N—H⋯N intermolecular hydrogen-bond and C—H⋯π interactions. [ABSTRACT FROM AUTHOR]
