【摘要】 合成了稀土硝酸盐与邻香草醛缩乙二胺（以Ｌ表示）的４种新固态配合物。通过元素分析，红外光谱、紫外光谱、差热一热重、摩尔电导及Ｘ－射线粉末衍射分析等手段。确定配合物的组成为ＬｎＬ（ＮＯ３）３（Ｌｎ＝Ｐｒ，Ｓｉｎ，Ｄｙ，Ｈｏ），并对其结构和某些物理化学性质进行了研究。更多还原

【Abstract】 our new solid complexes of lanthanoid nitrates with his-Schiff bases Ovanilin-ethylenediamine (L) were synthesized and characterized by elemental analysis,IR, UV, DTA-TG, molar conductance, X-ray powder diffraction analyses. The results showed that the compositions of the complexes were LnL (NO3)3 (Ln= Pr, Sm, Dy, Ho). Their possible structures were conjectured.更多还原
