Abstract

In the redox-active title compound, a 2,2-bipyridine derivative tethered to two N-methylpyridinium moieties as electron reservoirs. The asymmetric unit comprises one half of the divalent bpy cation together with a [PF₆]⁻ anion and a CH₃CN molecule. The crystal structure features hydrogen-bonding and π–π interactions.

The new redox-active title compound, C₂₄H₂₂N₆O₂²⁺·2PF₆⁻·2C₂H₃N, a 2,2-bipyridine derivative tethered to two N-methylpyridinium moieties as electron reservoirs, was synthesized and structurally characterized by ¹H NMR spectroscopy and single-crystal X-ray diffractometry. The asymmetric unit comprises one half of the divalent bpy cation together with a [PF₆]⁻ anion and a CH₃CN molecule. The cation is completed by inversion symmetry. The crystal structure features hydrogen-bonding and π–π interactions.
