Abstract
The title compound, tris(4,4′-bipyridinium) diarsenooctadecamolybdate(VI), (C10H10N2)3[As2Mo18O62], featuring protonated bipyridine molecules and a classical Dawson-type polyoxo-anion, has been synthesized under hydrothermal conditions. The polyoxoanions are linked together via the bipyridyl cations, acting as hydrogen-bond donors, generating a two-dimensional supramolecular network. The asymmetric unit contains 1.5 4,4′-bipyridinium (H2bpy) units, with an inversion centre in the central bond of the second H2bpy unit. The site symmetry of the anion is .

The cell e.s.d.'s are taken into account individually in the estimation of e.s.d.'s in distances, angles and torsion angles; correlations between e.s.d.'s in cell parameters are only used when they are defined by crystal symmetry
The weighted R-factor wR and goodness of fit S are based on F2, conventional R-factors R are based on F, with F set to zero for negative F2
