Shapes of undecanuclear clusters and undecacoordinated metal complexes

The structures of molecules that arrange eleven identical atoms in one, two or three dimensions are analyzed by means of continuous shape measures. In the case of 3-D molecules, they comprise metallic clusters, boranes, supramolecular architectures, and metal coordination spheres, examples of eight different polyhedra have been identified, and in some cases, also structures that fall along the minimal interconversion pathway between two such polyhedra are discussed.
