  摘要：

  The reactions of YCl3.6H(2)O, YBr3.6H(2)O and YI3.8H(2)O with Ph3PO, Ph3AsO, Ph2MePO, Me3PO, Me3AsO, o-C6H4{P(O)Ph-2}(2), (ppO(2)) and Ph2P(O)CH2P(O)Ph-2 (dppmO(2)) have been examined in EtOH or Me2CO solution. Complexes isolated in the solid state include [YX2(Ph3PO)(4)]Z (X = Cl, Br or I; Z = X or PF6), [YX3(Ph2MePO)(3)], [YCl2(Ph2MePO)(4)]PF6, [YCl(Ph3PO)(5)][SbCl6](2), [Y(Me3PO)(6)]X-3, [YX2(Ph3AsO)(4)]X, [Y(Me3AsO)(6)]Cl-3 and [YCl2(L-L)(2)]Cl (L-L = ppO(2) or dppmO(2)) which were characterised by analysis, IR and multinuclear (H-1, P-31{H-1} and Y-89) NMR spectroscopy and conductance measurements. The X-ray crystal structures of [YCl2(Ph3PO)(4)]Cl.2.5EtOH.H2O, [YBr2(Ph3PO)(4)]PF6.Et2O and [Y(Me3PO)(6)]Br-3 are reported and discussed. The solution speciation (in CH2Cl2) in the various systems was examined by variable temperature multinuclear NMR spectroscopy. The Y-89 NMR chemical shifts show systematic trends with donor set which are described. No reaction between these ligands and YF3.1/2H(2)O was observed. (C) 2002 Elsevier Science Ltd.
