'''4,4'-Bipyridine''' (4,4'-bipy) is a [[bipyridine]] which is mainly used as a precursor to N,N'-dimethyl-4,4'-bipyridinium [(C<sub>5</sub>H<sub>4</sub>NCH<sub>3</sub>)<sub>2</sub>]<sup>2+</sup>, known as [[paraquat]].  This species is [[redox|electroactive]], and its toxicity arises from the ability of this dication to interrupt biological [[electron transfer]].  Because of its structure, 4,4'-bipyridine can bridge between metal centres to give [[coordination polymers]].<ref>{{cite doi|10.1039/B606184B}}</ref>
