Synthesis and structures of homoleptic 2-methylpropane-2-thiolate complexes of samarium and ytterbium

Abstract

The homoleptic 2-thiolate complexes [Li(tmeda)]₃[Ln(SBu^t)₆(Ln = Yb 1 and Sm 2 have been synthesized and structurally charecterized; 1 from the reaction of YbCl₃ or YbI₂(thf)_x with LiSBu^t and 2 from Sml₂(thf)_x and LiSBu^t, in the presence of N,N,N′,N′-tetramethylethylenediamine (tmeda; thf = tetrahydrofuran).
