Bis{4,4′-[oxalylbis(azanediyl)]dipyridinium} octamolybdate

Abstract

In the crystal structure of the title compound, (C12H12N4O2)2[Mo8O26], the amino and pyridinium groups of the N1,N2-di(pyridinium-4-yl)oxalamide cations are hydrogen bonded to the O atoms of the centrosymmetric isopolyoxometalate β-[Mo8O26]4− anions, forming a three-dimensional supramolecular architecture.
