WebNov 5, 2024 · The lower valent pyridine complexes of these metals are composed of carbonyl and nitrosyl counterpart. The higher valent rhenium accommodates oxo ligands along with anionic monodentate and chelating ligands. The Mn (I) complexes quickly react with air and oxygen. Thus their preparation is carried out in a neutral atmosphere.
