Instead of the expected tetrahedral M 4 L 6 cage , a far more complicated M 12 L 18 cage forms when the bridging ligand shown reacts with Co II ions. The dodecanuclear cage has the topology of a tetrahedron in which all four vertices are truncated to reveal triangular faces. A bridging ligand spans each of the 18 edges of the metal cage, and all 12 metal–tris(chelate) centers are homochiral. [BF 4 ] − ions are located in the large central cavity and in the two‐dimensional cavities at the center of each face.
