【摘要】 本文由α—氨基—５—偶氮苯吡啶出发，分别与水杨醛、５硝基水杨醛及香草醛作用，合成了３种含有偶氮基团的杂环息夫碱．继而同三氯化钇反应，合成了３种新的配合物，通过元素分析、红外光谱、紫外可见光谱及热分析等方法研究了配合物的结构和性质．更多还原

【Abstract】 A new Schiff base was synthesized by the condensation of equimolar quantities of salicylaldehyde or o Vanillin and 2 amine 5 (4 nitro)phenylazo pyridine. Three new Yttrium Complexes of the type YL 3,YL " 3,YL 3Cl 3,Where L=nwely synthesized monobasic Schiff base were prepared in absolute ethanolic medium and characterized by elemental analysis, molar conductance, infrared spectra, electronic spectra and thermal analysis studies.更多还原
