3,4-Bis(2-pyrid-yl)-5-(3-pyrid-yl)-4H-1,2,4-triazole.

In the title mol-ecule, C(17)H(12)N(6), the 2-pyridyl rings in the 3- and 4-positions and the 3-pyridyl ring in the 5-position make dihedral angles of 29.78 (16), 67.06 (16) and 32.97 (16)°, respectively, with the triazole group. The dihedral angle between the two 2-pyridyl rings is 65.72 (15)°. The dihedral angles between the 3-pyridyl ring and the two 2-pyridyl rings in the 3- and 4-positions are 61.28 (15) and 63.11 (15)°, respectively. In the crystal, C-H⋯π and π-π inter-actions [centroid-centroid distance = 3.6248 (19) Å] link the mol-ecules, forming a two-dimensional network.
