Popis:	A polybipyridilium species has been prepared with four diquaternised bipyridine moieties around a durene core; mixed halide (bromide with iodide or with chloride) as well as single-anion (chloride) salts were studied, and their electrochemistry investigated. Three reduction processes are inferred producing a pink (di-reduced) species, a purple (tetra-reduced) species and a beige-coloured fully-reduced product. Mixed anion effects, in conjunction with dimer association and comproportionation, led to more complicated anodic electrochemistry than when only chloride anions were involved.
