Abstract

The first neutral, mononuclear 4f metal thiolates, [Sm(SAr)3] 1 and [Yb(SAr)2(dme)2]2, have been prepared and X-ray characterised [< Sm-S > 2.645(9) angstrom, < Yb-S > 2.756(8) angstrom], 1 from [Sm(CHR'2)3] + 3ArSH and 2 from [Yb(NR'2)2(dme)2] [obtained from Yb + Sn(NR'2)2]; 1 was not readily accessible from ArSH and Yb in liquid NH3, although replacing ArSH by Ar'OH yielded [Yb(OAr')2(thf)3] [Ar = C6H2But3-2,4,6; Ar' = C6H2But2-2,6-Me-4; R' = SiMe3, dme = (MeOCH2)2, thf = OC4H8].
