Big, bigger, biggest : Polyoxoniobate anions [HNb 27 O 76 ] 16− and [H 10 Nb 31 O 92 (CO 3 )] 23− incorporate pentagonal Nb(Nb) 5 building blocks; the central Nb ion is seven‐coordinate within the clusters. The Nb 27 species was observed using ESI‐MS, thus demonstrating some solution stability; the Nb 31 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.
