In the title compound, (C14H16N4)2[Mo8O26], the β-octamolybdate anion is centrosymmetric. N—H
O hydrogen bonds link the diimidazolium cations and the polyoxidoanions into a chain structure along [100]. π–π interactions between the imidazole rings and between the imidazole and benzene rings [centroid–centroid distances = 3.611 (2) and 3.689 (3) Å, respectively] connect the chains.

In the title compound, C12H6F2N2O2, the 2,2-difluoro-1,3-benzodioxole ring system is approximately planar [maximum deviation = 0.012 (2) Å] and its mean plane is twisted with respect to the pyrrole ring, making a dihedral angle of 2.51 (9)°. In the crystal, N—HN hydrogen bonds link the molecules into chains running along the a axis. π–π stacking is also observed between parallel benzene rings of adjacent molecules, the centroid–centroid distance being 3.7527 (13) Å.

In the title compound, C2H10N22+·C11H10O62−, the two acetate groups of the cation form dihedral angles of 74.2 (4) and 63.9 (5)° with the central benzene ring. In the crystal, N—HO hydrogen bonds link the cations and anions into layers parallel to the ab plane.
O hydrogen bonds link the cations and anions into layers parallel to the ab plane.
