Abstract
The first metal carbonyl derivatives, Ln[Co(CO)4]2·(THF)n(THF = tetrahydrofuran; n= 3,4), of divalent lanthanoids Ln(Ln = Sm, Eu, Yb) were prepared by treating Hg[Co(CO)4]2 with an excess of Sm, Eu, or Yb in THF at room temperature; the title complexes were also formed in high yields from the reaction of stoicheiometric amounts of the appropriate Lnl2 compounds and TICo(CO)4.
