Triphenyl[tris(tetrahydrofuran)]ytterbium, Ph3Yb(THF)(3) (1), was synt
hesized in high yields by the reaction of Yb with an excess of Ph2Hg o
r Ph3Bi in the presence of catalytic amounts of YbI2(THF)(4) as well a
s by the reaction of Ph2Yb(THF)(2) (2) with Ph2Hg or Ph3Bi. The crysta
l structure of complex 1 was studied by X-ray structural analysis.
