The title compound, {(C14H18N2)[Pb2I6]}n, consists of discrete 1,1′-dimethyl-4,4′-(ethane-1,2-di­yl)dipyridinium cations and one-dimensional [Pb2I6]n anions. The organic cation has an inversion center at the mid-point of the ethane C—C bond. In the anion, the PbII atom is coordinated by six I atoms in a distorted octa­hedral geometry. The I atoms bridge the PbII atoms into a polymeric chain running along [001]. These inorganic chains are separated by the isolated organic cations.
