4,4′-Bipyridin-1-ium bromide monohydrate
Abstract
The title compound, C10H9N2+·Br−·H2O, crystallizes in the orthorhombic crystal system. The structure consists of separate bipyridinium cations stacked along the a axis. The pyridine and pyridinium rings deviate from coplanarity by 29.6 (4)° about the C—C bridging bond. The Br− ions and the water molecules are situated between the stacks.
