[Co@Ge10]3-: an intermetalloid cluster with archimedean pentagonal prismatic structure.
Inorganic pentaprismane: The unusual structure of the anion [Co@Ge(10)](3-), which was obtained by the reaction of K(4)Ge(9) with [Co(C(8)H(12))(C(8)H(13))] in ethylenediamine, raises questions about chemical bonding in the anion. The Zintl ion cluster has virtual D(5h) symmetry and is a unique example of a ligand-free cluster that is not a deltahedron. The delocalized chemical bonding is represented in the picture by one of the bonding orbitals of the anion.
