A hybrid layered crystal containing polyoxomolybdate was successfully synthesized from reduced Mo-blue species as starting material. The hybrid crystal, [C5H5N(C16H33)]2[β-H2Mo8O26]·2C2H5OH (C16py-H2Mo8), was obtained as a single phase by the gradual oxidation of hexadecylpyridinium-Mo-blue (C16py-Mo-blue) hybrid. The X-ray structure analysis revealed that C16py-H2Mo8 comprised β-type octamolybdate anion with two protons (β-H2Mo8). The β-H2Mo8 anions and ethanol molecules of crystallization formed two-dimensional anionic layers. The pyridine rings of C16py did not attend to form the two-dimensional inorganic layers, and the interdigitated C16py bilayers were sandwiched by the β-H2Mo8 anionic layers with periodicity of 18.2 Å. These C16py-H2Mo8 hybrid layered crystals possibly work as a new class of proton conductor
