title: Arene-arene stacking in the revised structure of 2,2'-bipyridinium hexafluorophosphate.
abstract: The title compound, C(10)H(9)N(2)(+).PF(6)(-), crystallizes in space group P2(1)/c in a supercell doubled along b, rather than in the previously reported polar space group Pc [Milani, Anzilutti, Vicentini, Santi, Zangrando, Geremia & Mestroni (1997). Organometallics, 16, 5064-5075]. This new structure determination provides a more appropriate description of intra- and intermolecular parameters. The crystal packing is dominated by shifted pi-stacked arrangements of adjacent aromatic moieties.
