4,4 '-Bipyridinium Mu-Oxo-Bis(Fluorodioxochromate)

Abstract

In the cation of the title compound, (C<inf>10</inf>H<inf>10</inf>N <inf>2</inf>)[Cr<inf>2</inf>O<inf>5</inf>F<inf>2</inf>], a mirror plane passes through the N atoms of the two pyridine rings and the - C - C - bridge connecting them, while the two halves of the anion are symmetry-related across a mirror plane passing through the O atom at the centre of the anion. Chiral chains of the title compound are built up via N - H⋯O and N - H⋯F hydrogen bonds. © 2006 International Union of Crystallography. All rights reserved.
