The title compound, C 14 H 12 N 4 , is a disubstituted 1,2,4-triazole derivative. The triazole ring is planar and its dihedral angles with the attached pyridyl and methylphenyl rings are 25.2 (3) and 66.9 (3) , respectively. The crystal structure is stabilized by a number of CÐHÁ Á ÁN hydrogen bonds
