anionic iron complexes [Fe(2,2′-bipy)(mes)2]0/– (3/3–), form a homologous series of compounds which allow for an in-depth study of the interactions between metals and ligands. Single-crystal X-ray diffraction data, DFT calculations, and various spectroscopic and magnetic measurements indicate that the anionic complexes (1––5–) can be best formulated as M(II) complexes of the 2,2′-bipyridyl radical anion.
