title: 2-Methyl-1,2,4-triazolo[4,3-a]pyridin-2-ium tetra-fluoroborate.
abstract: 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] inter-molecular attractive inter-action. The ionic pairs form dimers via stacking inter-actions 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.
