Abstract: In the title compound, (C₁₄H₁₆N₄)₂[Mo₈O₂₆], the -octamolybdate anion is centrosymmetric. N-HO hydrogen bonds link the diimidazolium cations and the polyoxidoanions into a chain structure along [100]. - 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.
