Synthesis and properties of the benzenetricarbonylchromium derivatives of divalent samarium, europium, and ytterbium
Abstract
The title compounds, Ln[PhCr(CO)3]2·n(tetrahydrofuran) Lu = Sm, Eu, Yb, representing a new type of organometallic derivative of divalent lanthanides, were produced by the reaction of Hg[PhCr(CO)3]2 with an excess of Ln0 filings in tetrahydrofuran.
