稀土硝酸盐与咪唑配合物的合成及表征

Synthesis and characterization of three new complexes of rare earth nitrate with imidazole

合成了 L a( NO3 ) 3 · 4Im· 2 HNO3 · H2 O,Nd( NO3 ) 3 · 4Im· HNO3 · H2 O,Eu( NO3 ) 3 ·3 Im· HNO3 · H2 O三种新配合物。测定了它们的溶解性 ,用 EDTA容量法和元素分析确定了它们的组成 ,通过红外、紫外及 X-射线对它们进行了表征。

The three new coordination compounds that they are La(NO 3) 3·4Im·2HNO 3·H 2O,Nd(NO 3) 3·4Im·HNO 3·H 2O and Eu(NO 3) 3·3Im·HNO 3·H 2O have been prepared,where Im is a abbreviation of imidazole.The composition and structure of the prepared compounds have been determined by the chemical analysis,elemental analysis,IR spectra,UV spectra,X ray powder diffraction and soluency.
