The two butanediyl ligands in the novel manganate(+ III ) 1 , which was synthesized from manganocene, naphthalenepotassium, ethene and pyridine, are formed from four ethene molecules. In contrast, when manganocene is reduced with naphthalenelithium in the presence of trimethylphosphane [Li(tmeda) 2 ]‐[Mn(η 4 ‐C 10 H 8 )(PMe 3 ) 3 ] can be isolated. This diamagnetic manganate(—I) contains an η 4 ‐bound naphthalene ligand.
