Description:
In the title salt, C7H8N3+·BF4−, the 1,2,4-triazolo[4,3-a]pyridinium cation is planar [maximum deviation of 0.016 (2) Å for all non-H atoms]. The cation and anion constitute a tight ionic pair with an F...N [2.911 (4) Å] intermolecular attractive interaction. The ionic pairs form dimers via stacking interactions between inversion-related cations, the normal distance between the cation planes being 3.376 (5) Å. The dimers are packed in stacks along the a axis and linked via C—H...F hydrogen bond, forming a three-dimensional network.
