摘　　要：合成邻香兰素(2-羟基-3-甲氧基苯甲醛)与α-萘胺Schiff碱硝酸稀土配合物[LnL_2(NO_3)_2NO_3(Ln:镧系元素,L:Schiff碱配体)。配合物由一个中心稀土离子,两个Schiff碱和三个硝酸根组成,两个Schiff碱都是氮、氧双配位,两个硝酸根是双齿配位,另一硝酸根在配合物外界。中心稀土离子是八配位的,满足稀土八配位的稳定结构。Coordination compounds of rare earth nitrate with Schiff base derived from o-vaniilin (2-hydroxy-3-methoxy-benzaldehyde) and 1-naphthy]amine have been prepared and characterized.On the basis of elemental analyses, infrared spectra, Raman spectra, ultraviolot visible spectra, molar conductance and thermal analyses, it is concluded that two Schiff bases and two nitrate groups are bound to the rare earth ion. One nitrate group is found in the outer coordination sphere. The general formula of the coordination compounds, [LnL_2(NO_3)_2]NO_3(Ln=La, Pr, Nd, Sm, Eu, Tb, Dy, Ho, Tin, Yb; L=Schiff base ligand), was given. The lanthanide ions in the coordination compounds exhibit coordination of eight.
