Organoamido- and aryloxo-lanthanoids. 26: Syntheses of bis(aryloxo)halogenoytterbium(III)

Oxidation of [Yb(OArR)2(THF)3] (OArR = OC6H2-2,6-tBu2-4-R; R = H, Me, tBu) with HgX2 or with (CH2X)2 (X = Cl, Br, I) in THF yields [Yb(OArR)2X-(THF)2], whilst [Yb(OArMe)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(OArMe)2I(THF)2] to be a five coordinate monomer, in which ytterbium has distorted square pyramidal stereo-chemistry with mutually trans OArMe and THF ligands in the square plane and an apical iodide. Attempts to grow single crystals of [Yb(OArH)2Cl(THF)2] yielded [Yb(OArH)2-OH(THF)]2, shown to be an hydroxo-bridged dimer with five-coordinate ytterbium by X-ray crystallography. ?
