Here three Nb-POM clusters were isolated and structurally characterized; [Nb₁₄ O₄₀ (O₂ )₂ H₃ ]^14- , [((UO₂ )(H₂ O))₃ Nb₄₆ (UO₂ )₂ O₁₃₆ H₈ (H₂ O)₄ ]^24- , and [(Nb₇ O₂₂ H₂ )₄ (UO₂ )₇ (H₂ O)₆ ]^22- , that effectively capture the aqueous Nb-POM species from pH 7 to pH 10. These Nb-POMs illustrate a reaction pathway for control over speciation that is driven by counter-cations (Li⁺ ) rather than pH. The two reported heterometallic POMs (with UO₂ ²⁺ moieties) are stabilized by replacing labile H₂ O/HO-Nb=O with very stable O=U=O. The third isolated Nb-POM features cis-yl-oxos, prior observed only in group VI POM chemistry. Moreover, with these actinide-heterometal contributions to the burgeoning Nb-POM family, it now transects all major metal groups of the periodic table.21:T429,The self-assembly mechanisms of polyoxometalates (POMs) are still a matter of discussion owing to the difficult task of identifying all the chemical species and reactions involved. We present a new computational methodology that identifies the reaction mechanism for the formation of metal-oxide clusters and provides a speciation model from first-principles and in an automated manner. As a first example, we apply our method to the formation of octamolybdate. In our model, we include variables su
