Structure determination at 150\u2005K from a two-component twin crystal reveals the non-symmetrical n-shaped dication, where two pyridine\u2013imidazole fused cores bearing pendant pyridyl rings are linked by an ethylene bridge. The fused five- and six-membered rings are almost coplanar with the largest deviation from the mean plane being 0.019\u2005\u00c5 for a nitrogen atom of one of the rings. The pendant pyridyl groups are twisted by 42.14\u2005(11) and 46.47\u2005(11)\u00b0 with respect to the planes of the adjacent imidazo[1,5-\n                    <jats:italic>a<\/jats:italic>\n                    ]pyridinium cores.
