Abstract
The complexone‐like tetraazamacrocycle 1 (LH~4~) forms a series of metal complexes with Co^2+^, Ni^2+^, Cu^2+^ and Zn^2+^ (M^2+^) of the type MLH~2~, ML^2−^ and M~2~L, which have been isolated and characterized by VIS., IR. and NMR. spectroscopy. Based on these results tentative structures for the different species are proposed.
