## Abstract 12,12‐Dimethyl‐1,4,7,10‐tetraazacyclotridecane (I), 11,13‐dimethyl‐1,4,7,10‐tetraazacyclotridecane (II), 11,11,13‐trimethyl‐1,4,7,10‐tetraazacyclotridecane (III) and 1,4,7,10,12,12‐hexamethyl‐1,4,7,10‐tetraazacyclotridecane (IV) have been synthesized and their properties are described.
An extremely high thermal and chemical stability as well as a unique "out-of-plane" position of the metal atom is shown by the first stable transition metal complexes formed with the proton sponge 1 as the ligand. The properties of these complexes await wide application in catalysis and medicine.
