Abstract

The title compound, C16H15N5O2, adopts the shape of the letter L with the dihedral angle between the outer pyridyl rings being 78.37 (5)°; the dihedral angles between the central pyrazolyl ring (r.m.s. deviation = 0.0023 Å) and the methyl-ene-bound pyridyl and methyoxypyridyl rings are 77.68 (5) and 7.84 (10)°, respectively. Intra-molecular amide-N-H⋯N(pyrazol-yl) and pyridyl-C-H⋯O(amide) inter-actions are evident and these preclude the participation of the amide-N-H and O atoms in inter-molecular inter-actions. The most notable feature of the mol-ecular packing is the formation of linear supra-molecular chains aligned along the b-axis direction mediated by weak carbonyl-C=O⋯π(triazol-yl) inter-actions. An analysis of the calculated Hirshfeld surfaces point to the importance of H⋯H (46.4%), C⋯H (22.4%), O⋯H (11.9%) and N⋯H (11.1%) contacts in the crystal.
