Into the Next Dimension: Nanometer-Sized, Oligonuclear Coordination Compounds with C₃-Symmetric Ligands

Nanometer-sized cavities are present in oligonuclear coordination compounds formed in molecular self-assembly processes from C₃-symmetric ligands and appropriate metal complex fragments. The structures obtained can be described as basic polyhedra such as tetrahedron, hexahedron, or octahedron (see picture).
