Abstract

Reaction of the divalent phosphinoytterbocene Yb(C₅H₄PPh₂)₂(THF)(THF = tetrahydrofuran) with mercuric chloride in THF or toluene yields mercury metal and the lanthanoid(III) complex Yb(C₅H₄PPh₂)₂Cl. An X-ray crystal structure of the compound revealed the presence of two independent chloride-bridged dimers (one centrosymmetric, one non-centrosymmetric, in a ratio of 1:2) with uncoordinated Ph ₂P groups and pseudo-tetrahedral eight coordination (two η⁵-C₅H₄PPh₂ and two η-Cl ligands) at ytterbium. The dimers differ in the arrangement (syn, anti) of the Ph₂P groups. Solution spectroscopic data suggest that there is P-Yb bonding in toluene.
