| 摘 要： | 本文报道了14种新的固态稀上元素配合物(除C_e,P_m,L_u外),它们是用稀土的硝酸盐与1,4—双(1′—苯基—3′—甲基—5′—氧代吡唑—4′—基)—1,4苯二酮(简写为H_2L)在乙醇—水溶液中,于PH=5.8～6.0条件下反应而制得的.配合物的分子式为RE_2L_3·nH_2O(RE=La,Nd,n=8,RE=Pr,Sm,n=6.RE=Eu,Gd,Tb,Dy,Ho,Er,Tm,Yb,Sc,Y,n=5).用化学分析,元素分析,紫外,红外、质子核磁共振,热分析和荧光谱对配合物进行了研究.根据以上研究,认为配合物具有双核结构.

| Abstract: | This paper reported that fourteen new solid complexes of rare earth (except Ce,Pm, Lu) Synthsized by the reaction of rare earth nitrates with 1,4-bis-(1'phenyl - 3' -methyl - 5'-pyrazolone -4'-)Phthaldione (Simplified as H2L) in ethanol aqueous solution at pH = 5. 8-6. 0. these complexes with a formula: RE2L3 ?nH2O (RE = La, Nd, n = 8. RE = Pr, Sm,n = 6. RE = Eu,Gd,Tb,Dy,Ho,Er,Tm,Yb,Sc,Y,n = 5). The properties of these complexes were studied infrared,ultravilet,proton magnetic resonance,fluorescence spectrum and DTA-TG. On the basis of all above investigation it can be thought rare earth complexes are binuclear structure. |
