- Abstract
In this paper, we describe the synthesis, characterization, and stability studies of new FeII complexes prepared with the ligand N,N'-dimethyl-N,N'-bis(4-nitropyridin-2-ylmethyl)ethane-1,2-diamine (L4²NO2). The properties of these complexes were probed by magnetic, spectroscopic, and electrochemical techniques and compared with those of the parent complexes prepared with the unsubstituted ligand N,N'-dimethyl-N,N'-bis(pyridin-2-ylmethyl)ethane-1,2-diamine (BPMEN or L4²). The para functionalization of the pyridine moieties with π-accepting nitro groups increases the ligand-field strength and the Lewis acidity of the metal center without altering the stability of the complex.
