چکیده
In the title compound, C(9)H(10)N(4), the phenyl and triazole rings make a dihedral angle of 38.80 (2)°. N-H⋯N hydrogen bonds link the mol-ecules, forming centrosymmetric R(2) (2)(8) rings; these rings are inter-connected through a C(5) chain, building up a zigzag layer parallel to the (100) plane.
