title: Bis{4,4'-[oxalylbis(aza-nedi-yl)]dipyridinium} octa-molybdate.
abstract: In the crystal structure of the title compound, (C(12)H(12)N(4)O(2))(2)[Mo(8)O(26)], the amino and pyridinium groups of the N(1),N(2)-di(pyridinium-4-yl)oxalamide cations are hydrogen bonded to the O atoms of the centrosymmetric isopolyoxometalate β-[Mo(8)O(26)](4-) anions, forming a three-dimensional supra-molecular architecture.
