2-(5-{6-[5-(Pyrazin-2-yl)-1H-1,2,4-triazol-3-yl]pyridin-2-yl}-1H-1,2, 4-triazol-3-yl)pyrazine

Abstract

In the title molecule, C 17H 11N 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 threedimensional network structure generated by intermolecular N - H⋯N hydrogen bonds. The crystal structure is further consolidated by π-π stacking [centroidtocentroid distances 3.599 (10) and 4.769 (13) Å].
