Two {Mo36}-containing polymolybdates: Synthesis, crystal structures, and spectral characterizations

Two polyanion clusters [Mo36O108(NO)4(H2O)16]12 − (1) and [Mo36O112(H2O)16Cu0.5(H2O)2]7 − (2) were obtained through ‘one-pot’ reaction at ambient temperature and pressure. Both of 1 and 2 consist of {Mo36} anionic clusters. Interestingly, compound 2 represents a case that the transitional metal copper is anchored into the framework of a giant {Mo36} isopolyanion.
