The last decade saw an explosion of research on the mixed-valence giant-cluster polyoxomolybdates,(1) among which the ring-shaped {Mo154} anion has the largest number of derivatives. Their synthetic conditions depend on acidity, temperature, reaction time, concentration of Mo, reducing reagent, and other chemical components present in the system. We focused on the effect of the acidity on determining the nuclearity of {Mo154} family polyoxometalates and carried out an systematic crystal structure determinations, which was enabled by the use of synchrotron radiation.
