Abstract
The first neutral, mononuclear 4f thiolates, [Sm(SAr)3]1 and [Yb(SAr)2(dme)2]2, have been prepared, and X-ray characterised [ 2.645(9)Å, 2.756(8)Å], 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 = C6H2But 3-2,4,6; Ar′= C6H2But 2-2,6-Me-4; R′= SiMe3′ dme =(MeOCH2)2, thf = OC4H8].Keywords
