Abstract

Oxidation of [Yb(OAr^R)₂(THF)₃] (OAr^R = OC₆H₂-2,6-tBu₂-4-R; R = H, Me, tBu) with HgX₂ or with (CH₂X)₂ (X = Cl, Br, I) in THF yields [Yb(OAr^R)₂X-(THF)₂], whilst [Yb(OAr^Me)₂Cl(THF)₂] was also obtained by oxidation of the appropriate Yb(II) aryloxide with C₂Cl₆ in THF. An X-ray crystal structure determination has shown [Yb(OAr^Me)₂I(THF)₂] to be a five coordinate monomer, in which ytterbium has distorted square pyramidal stereo-chemistry with mutually trans OAr^Me and THF ligands in the square plane and an apical iodide. Attempts to grow single crystals of [Yb(OAr^H)₂Cl(THF)₂] yielded [Yb(OAr^H)₂-OH(THF)]₂, shown to be an hydroxo-bridged dimer with five-coordinate ytterbium by X-ray crystallography.
