The synthesis and characterization of a series of polyantimony anionic clusters are reported. The products [(NbCp)(2)Sb-10](2-), [MSb13](3-) (M = Ru/Fe), and [MSb15](3-) (M = Ru/Fe) were isolated as either K(18-crown-6) or K([2.2.2]-crypt) salts. The Sb-10 ring contained in the [(NbCp)(2)Sb-10](2-) cluster can be viewed as an extension of two envelope-like cyclo-Sb-5 units and represents by far the largest monocyclic all-antimony species. The clusters [MSb13](3-) and [MSb15](3-) (M = Ru/Fe) illustrate the variability of crown-like Sb-8 ring motifs and reveal the fusion of different antimony fragments featuring unique Sb-Sb chain-like units. The reported synthetic approaches involve the fabrication of a variety of distinctive polyantimony anionic clusters, enhancing our understanding of the coordination chemistry of heavier group 15 elements.
