The title compound, (C18H18N6)2[Mo8O26], was produced by hydrothermal reaction of an acidified aqueous solution of Na2MoO4 and 1,1′-bis(pyridin-4-ylmethyl)-2,2′-bi-1H-imidazole (hereafter L). The structure consists of the β-octamolybdate anions having a crystallographic center of symmetry and protonated [H2 L]2+ cations. The [H2 L]2+ cations link β-octamolybdate anions, generating a two-dimensional hydrogen-bonded supramolecular sheet.

In the title compound, C7H7N2 +·NO3 −, all atoms except the methyl H atoms lie on a crystallographic mirror plane. The interlayer distance, including that between aligned N atoms from alternating cations and anions in adjacent layers, is exceptionally short at 3.055 (1) Å. Two-dimensional C—H...O hydrogen-bonded networks link cations to anions, while C—H...N interactions link cations within each layer. Anion–π interactions with the cations assist in binding the layers together.
