of alkoxy protecting groups into the vacant sites of lacunary polyoxometalates (POMs) was demonstrated. By reacting organic‐solvent‐soluble trivacant lacunary Keggin‐type POMs with methanol, six methoxy groups were introduced into the vacant sites. These monodentate alkoxy ligands could protect the reactive vacant sites and also easily be dissociated by hydrolysis. In contrast, the multidentate alkoxy ligands of pentaerythritol showed high resistance against hydrolysis, which allowed the synthesis of dimeric inorganic–organic–inorganic hybrid structures with the same or different heteroatoms.
