Description
Book SynopsisWhereas tetradentate (OSSO)-type ligands mostly allow for the preparation of mononuclear transition metal complexes, lignads that feature two or more of the structurally related (ONNO)-type subunits may give access to multinuclear heterometallic complexes. +IV, +V and *VI stabilized by tetradentate (OSSO)-type ligands led to the development of a tris(ONNO)-type ligands revealed a new approach toward heterometallic 3d transition metal complexes that resolves the limitations of core/shell template directed synthesis and avoids metal cooperative effects resulting in magnetic interactions of the paramagnetic center and in enhanced catalytic activity in transformations of heterocumulenes with epoxides. This thesis further contributes to the field of mono- and tetranuclear metal complexes stabilized by (OSSO)- or tris(ONNO)-type ligands. Based on these ligands, the stractural, magnetic and electrochemical propeties of various complexes are reported.
