4,4'-{[(2,2'-Bi-pyridine)-5,5'-dicarbon-yl]bis-(aza-nedi-yl)}bis-(1-methyl-pyridin-1-ium) bis-[hexa-fluorido-phosphate(V)] acetonitrile disolvate.

Abstract

The new redox-active title compound, C₂₄H₂₂N₆O₂ ²⁺·2PF₆ ^-·2C₂H₃N, a 2,2-bi-pyridine derivative tethered to two N-methyl-pyridinium 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 mol-ecule. The cation is completed by inversion symmetry. The crystal structure features hydrogen-bonding and π-π inter-actions.
