Özet
The first neutral, mononuclear 4f thiolates, [Sm(SAr)3] 1 and [Yb(SAr)2(dme)2] 2, have been prepared, and X-ray characterised [<Sm-S> 2.645(9) Å, <Yb-S> 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 = C6H 2But3-2,4,6; Ar? = C6H 2But2-2,6-Me-4; R? = SiMe 3? dme = (MeOCH2)2, thf = OC 4H8].
