摘要
乙醇-水混合体系中合成了15种新的稀土元素的固态配合物,通过元素分析和化学分析确定了配合物的化学组成为RE_2(BPMPPD)_3·nH_2O和Ce(BPMPPD)_2·6H_2O(BPMPPD为1,5-双(1′-苯基-3′-甲基-5′-氧代吡唑-4′-基)戊二酮-[1,5]),对配合物的荧光光谱等性质进行了研究。
The present paper covers fifteen new solid complexes of rare earth synthsized by the reaction of rare earth nitrates and (NH4)2Ce(SO4)3 with BPMPPD in the aqueous solution of ethanol. The compounds with a general formula: RE2(BPMPPD)3.nH2O(Re= La, Pr, Nd, Sm, Eu, Gd, Tb, Dy, Ho, Er, Tm, Yb, Y. n = 3-7) ,Ce(BPMPPD)2.6H2O and (Y-Eu)2. (BPMPPD)3.8H2O(Y:95%; Eu: 5% ), were obtained and characterized by elemental analysts, chemical analysis, IR, DTA-TG, 1H NMR and fluorescence.
