摘要：

(Figure Presented) Big, bigger, biggest: Polyoxonlobate anions [HNb 27O76]16- and [H10Nb 31O92(CO3)]23- incorporate pentagonal Nb(Nb)5 building blocks; the central Nb ion is seven-coordinate within the clusters. The Nb27 species was observed using ESI-MS, thus demonstrating some solution stability; the Nb31 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. © 2010 Wiley-VCH Verlag GmbH & Co. KGaA.
