Neue Beiträge zur Chemie des Mangans: Synthese und Strukturen zweier monomerer Mn^II1‐Verbindungen und eines hexanuklearen Mn^II/III1‐Komplexes

New Contributions to the Chemistry of Manganese: Syntheses and Structures of two Monomeric Mn II Compounds and a Hexanuclear Mn II/III Complex Two novel mononuclear manganese(II) complexes, Mn[OSi(O t Bu) 3 ] 2 ·(Py) 3 ( 2 ) and Mn[PhC 6 H 4 C(NSiMe 3 ) 2 ] 2 ·THF ( 3 ), and a hexanuclear mixed‐valence manganese(II/III) complex Mn 6 O 2 (O 2 C t Bu) 10 ·(Py) 4 ( 5 ) have been prepared, and their structures have been determined by X‐ray crystal structure analyses.
