Metal complexes with tripodal hexadentate ligands containing three bidentate arms have a pair of optical isomers, that is Δ form and Λ form. We have prepared the metal complexes with two types of tripodal ligands. The complexes are not only mononuclear ones but also multinuclear and self-assembled supramolecular ones. Here, we describe the structures and properties with the emphasis on chirality-related features of them.
