Base-Free and Bisphosphine Ligand Dialkylmanganese(II) Complexes as Precursors for Manganese Metal Deposition

The solid-state structures and the physical, solution magnetic, solid-state magnetic, and spectroscopic (NMR and UV/vis) properties of a range of oxygen- and nitrogen-free dialkylmanganese­(II) complexes are reported, and the solution reactivity of these complexes toward H2 and ZnEt2 is described. The compounds investigated are [{Mn­(μ-CH2SiMe3)2}∞] (1), [{Mn­(CH2CMe3)­(μ-CH2CMe3)2}2{Mn­(μ-CH2CMe3)2Mn}] (2), [Mn­(CH2SiMe3)2(dmpe)] (3; dmpe = …
