Fluorinated thiolates of divalent and trivalent lanthanides. Ln-F bonds and the synthesis of LnF(3)
Fluorinated thiolates form particularly stable chalco-genolate complexes with the lanthanides. Both Sm-(SC6F5)(3) and Eu(SC6F5)(2) were prepared by transmetalation. The Sm compound is a dimer in the solid state, with a pair of bridging thiolate ligands connecting the two sm(III) ions, while the Eu(II) compound is polymeric. In both compounds there are clearly defined Ln-F interactions. Thermolysis of the Sm compound gives SmF3 and (C6F4S), (n = 2, 3, 4).
