In the title mol­ecule, C 17 H 11 N 11 , the five rings are almost coplanar [maxium deviation 0.1949 (1) Å]. The dihedral angles between the two pyrazine rings and the two triazole rings are 1.52 (4) and 2.51 (5)°, respectively. The central pyridine ring forms dihedral angles of 5.57 (1) and 1.71 (1)° with the two triazole rings. The crystal packing consists of a three-dimensional network structure generated by inter­molecular N—H⋯N hydrogen bonds. The crystal structure is further consolidated by π–π stacking [centroid-to-centroid distances 3.599 (10) and 4.769 (13) Å].
