本工作合成了希土硫氰酸盐及希土高氯酸盐与2,4-二酮-16-冠-5醚的配合物。经元素分析其组成为Ln(NCS)_3·C_(11)H_(13)O_7·nH_2O(Ln=La,Ce,Pr,Nd,n=1,1.5)、Ln(ClO_4)_3·C_(11)H_(18)O_7·mCH_3CN·nH_2O(Ln=La,Nd,m=0,n=1,2;Ln=Er,m=1,n=1),进行了红外光谱、紫外光谱、电导测定、差热分析等,对配合物的性质及合成条件进行了探讨,发现配体通过环上醚氧与希土离子相键合,环上羰基也有一定的作用,此外不同的阴离子(NCS~-、ClO_4~-)与希土金属离子配位情况不同。
In this work, a mixture of rare earth thiocyanate and rare earth perchlorate with 2,4-dione-16-crown-5 ether was synthesized. The composition of Ln (NCS) _3 · C_ (11) H_ (13) O_7 · nH_2O (Ln = La, Ce, Pr, Nd, n = 1,1.5) and Ln (ClO_4) _3 · C_ ), H 18 O 7 · mCH 3 CN · nH 2 O (Ln = La, Nd, m = 0, n = 1,2; Ln = Er, m = 1, n = 1) , Differential thermal analysis and so on, the nature of the complex and synthesis conditions were discussed and found that the ligand through the ring ether ether oxygen and the earth ions, the carbonyl ring also has a certain role, in addition to different anions (NCS ~ , ClO_4 ~ -) is different from the coordination of rare earth metal ions.
