Abstract
Treatment of molybdenum(II) acetate with thioether functionalized silylamides R2Si(NLi‐C6H4–2‐SR')2 leads to the formation of dinuclear MoII complexes [Mo2{R2Si(NC6H4‐2‐SR')2}2]. According to X‐ray crystal structure analyses the complexes [Mo2{Me2Si(NC6H4‐2‐SMe)2}2] and [Mo2{Ph2Si(NC6H4‐2‐SPh)2}2] comprise a Mo2‐unit which is coordinated by two μ‐κ‐N,N' silylamide ligands. The coordination sphere around the molybdenum atoms consists of two amide nitrogen atoms and two thioether sulfur atoms in a distorted square‐planar arrangement. The Mo‐Mo distances are 211.0(1) and 211.7(1) pm, resp. In the complex [Mo2{Ph2Si(NC6H4‐2‐SMe)2}2] the silyl amide units act as tetradentate κ‐N,N',S,S'chelating ligands and the Mo‐Mo distance is 218.6(1) pm.
