合成了18-冠-6(Ⅰ)与Ce(NO_3)_4、Ce(ClO_4)_4、Ce(NO_3)_3及Y(NO_3)_3四种配合物,以及二苯并-18-冠-6(Ⅱ)与Ce(ClO_4)_4、Gd(ClO_4)_3、Eu(ClO_4)_3及Y(NO_3)_3四种配合物。对这八种配合物进行元素分析,摩尔电导、红外光谱、紫外光谱、差热和热重分析等性质测试。结果表明:1.在乙晴中硝酸盐配合物属非电离型,高氯酸盐配合物属电离型;2.每个金离于的配位数约为9或大于9;3.它们的化学式分别是:LnA_(3[4]) Ⅰ xH_2O(Ln=Ce(Ⅳ),Y;A=ClO_4~-或NO_3~-;x=0,3,4.)和LnA_(3[4]) ⅡxH_2O(Ln=Ce(Ⅳ),Gd,Eu和Y;x=0,1,3)。并着重讨论了Ce(NO_3)_(3[4]) Ⅰ,Ce(NO_3)_(3[4]) Ⅱ和Ce(NO_3)_(3[4]),四苯基-18-冠-6(Ⅲ)的热稳定性变化规律。
The complexes of Ce (NO_3) _4, Ce (ClO_4) _4, Ce (NO_3) _3 and Y_ (NO_3) Ⅱ and Ce (ClO_4) _4, Gd (ClO_4) _3, Eu (ClO_4) _3 and Y (NO_3) _3 four complexes. The eight complexes were characterized by elemental analysis, molar conductance, infrared spectra, ultraviolet spectra, differential thermal and thermogravimetric analysis. The results show that: 1. In nitrate cyanide nitrate complexes are non-ionizing type, perchlorate complex ionization type; 2. Each gold separation coordination number is about 9 or greater than 9; 3. Their The chemical formulas are: LnA_ (3 [4]) Ⅰ xH_2O (Ln = Ce (Ⅳ), Y; A = ClO_4 ~ - or NO_3 ~; x = 0,3,4) and LnA_3 [4] IIxH2O (Ln = Ce (IV), Gd, Eu and Y; x = 0, 1, 3). The effects of Ce (NO_3) _3 [4] Ⅰ, Ce (NO_3) _3 [4] Ⅱ and Ce (NO_3) _3 [4] 6 (Ⅲ) of the thermal stability of the law.
