Abstract
Crystals of the title compound, C17H15N2 +·BF4 -, were unexpectedly grown from crystallization attempts of [Pt(4,4'-bpy)4](BF4)2 [Smith et al. (2019 ▸). Comments Inorg. Chem. 39, 188-215] using toluene and aceto-nitrile. The tetra-fluoro-borate anion and the central pyridinium ring of the cation are disordered, with atomic site occupancies close to ½. The tolyl group of the cation has a 75.31 (11)° twist relative to the unsubstituted pyridyl group. This rotation allows for a centrosymmetric dimer of cations with weak hydrogen bonding between the pyridyl nitro-gen atom and a methyl H atom on the neighbouring cation.
