1-(2-Methyl­phen­yl)-4,4′-bipyridin-1-ium tetra­fluorido­borate

ABSTRACT: In the crystal structure of the title compound, the cations pack as dimers connected by weak hydrogen bonds between the pyridyl nitro­gen and a methyl hydrogen atom on the neighbouring cation. 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 aceto­nitrile. The tetra­fluoro­borate 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 nitro­gen atom and a methyl H atom on the neighbouring cation.
