摘要： 合成了一类新的十氢十硼酸氧化吡啶合稀土(Ⅲ)配合物,其化学式为[Ln(PYO)7]2、(B10H10)3,式中Ln=Nd,Sm,Eu,Gd,Ho,Er,Tm,Yb;PYO=氧化吡啶。观测了配合物的一般性质以及它们的IR光谱、Raman光谱、UV光谱和摩尔电导率、TG-DTA图谱等特性,并探讨了它们的热行为。

Abstract: The pyridine oxide(PYO)complexes of rare earth(Ⅲ)decahydrodecabo-rates were prepared by the reactions between Ln2(B10H10)3nH2Oand PYOin ethanol medium.These complexes were characterized by elemental analysis,electro-conductance,IR,Raman,UVspectra,and TG-DTA They have the follow ing formulae [Ln(PYO)7]2(B10H10)3(Ln=Nd,Sm,Eu,Gd,Ho,Er,Tm,Yb).The PYOis boned to the rare earth via the oxygen atom.The molar conductance data indicate that these complexes are ionic and behave as 2:3 electro-tyles in water.These complexes are thermally stable and their thermal behavior were approached.
