Abstract
Big, bigger, biggest: Polyoxoniobate anions [HNb<sub>27</sub>O<sub>76</sub>]<sup>16−</sup> and [H<sub>10</sub>Nb<sub>31</sub>O<sub>92</sub>(CO<sub>3</sub>)]<sup>23−</sup>incorporate pentagonal Nb(Nb)5 building blocks; the central Nb ion is seven-coordinate within the clusters. The Nb<sub>27</sub> species was observed using ESI-MS, thus demonstrating some solution stability; the Nb<sub>31</sub> species is chiral and incorporates a carbonate ligand in the outer section of the cluster. The two species are the largest polyoxoniobates reported to date.
