| 摘要: 本文报道在无水乙醇中合成了TTA和TPPO与除Tm和Lu外的整个系列希土离子的三元配合物。实验发现,对于La、Ce形成组成为RE(NO3)2(TTA)(TPPO)3的配合物;而对于其余希土离子则得到组成为RE(NO3)(TTA)2(TPPO)2的配合物。培养出了Pr(NO3)(TTA)2(TPPO)2配合物的单晶,测定了它的分子和晶体结构。根据结构数据讨论了配合物的红外和紫外光谱。 |

| Abstract: A series of ternary complexes of RE(NO3)2(TTA)(TPPO)3(RE = La, Ce) and RE-(NO3)(TTA)2(TPPO)2(RE = Pr-Er, Yb,Y) have been perpared. Their physico-chemical properties have been studied with conductance, UV and IR spectroscopies. The crystal structure of Pr(NO3)(TTA)2(TPPO)2 has been determined. It is triclinic, space group PI, FW=993.68; a=11.0359(10), b=11.8660(36), c= 12.6230(22)Å, a= 65.58(2), β = 77.91(1), r = 62.07(2)°;V= 1329.6Å3, Z=l, Dc= 1.241g/cm3. F(000) = 604, final R is 0.063. |
