Article abstract of DOI:10.1039/c39910000779

The reaction between YbI2 and Kt)3> affords the diamagnetic ytterbium bis-stannyl derivative 1 (Nep = 2,2-dimethylpropyl and thf = tetrahydrofuran) which has been characterised by multinuclear NMR spectroscopy (119Sn and 171Yb) and X-ray crystallography: reaction of 1 with two equivalents of ArOH (ArOH = 2,6-di-tert-butyl-4-methylphenol) or C5Me5H results in the elimination of Sn(CH2But)3H to afford the known complexes and respectively whereas the reaction with one equivalent of ArOH or C5Me5 resultsin the formation of the novel mixed ligand complexes t)3>(thf)2> and t)3>(thf)2>.
