芳香胺及其氮氧化物合稀土配合物的研究(Ⅳ)

Studies on Rare Earth Complexes with Heterocyclic Aromatic Amine and Their N-Oxide(Ⅳ)

在非水溶剂中合成出Ｇｄ，Ｔｂ，Ｄｙ，Ｈｏ，Ｅｒ硝酸盐与２，２’－联喹咐－Ｎ，Ｎ’－二氧 化物（简写为ＢｉｑＯ２）的新型固体配合物Ｌｎ（ＢｉｑＯ２）（ＮＯ３）３·ｎＨ２Ｏ（Ｌｎ＝Ｇｄ， ｎ＝１；Ｌｎ＝Ｔｂ，Ｄｙ．Ｈｏ．Ｅｒ：ｎ＝２）。通过元素分析、红外光谱、紫外光谱、Ｘ光 粉末衍射物相分析、差热－热重分析、溶解性及摩尔电导等测定，研究了配合物的有关 性质．５个新配合物在紫外光（２５４ ｎｍ）的照射下均可发出蓝紫色的荧光．

The new solid complexes Ln(BiqO2) (NO 3)3.nH2O (BiqO2=2,2'-biquino-line-N,N'-dioxide; Ln=Gd, n=1; Ln=Tb, Dy, Ho, Er, n=2) are synthesi-zed in nonaqueous solvents These complexes are characterized by elemental analyses, IR and UV spectra, X-ray powder diffraction, differential thermal analyses(DTA) and thermogravimetry(TG),solubilities and molar conductances.
