A supramolecular compound, [Himi]₆[As₂Mo₁₈O₆₂].11H₂O (1) (imi = imidazole), has been synthesized and characterized by single crystal X-ray analysis, IR spectra, thermal gravimetric analysis, electrochemical and elemental analysis. The crystals are monoclinic, P 2(1)/n, a = 14.9529(8) Å, b = 20.9521(11) Å, c = 25.2464(13) Å, β = 93.8130(10)º, V = 7892.1(7) Å³, Z = 4. X-ray diffraction indicated that protonated imidazole cation and polyanion were linked together through electrostatic interactions and intermolecular forces (hydrogen bonding).
