合成出化学式为[Eu(pic)_3(TDD)]·2CH_3CN和[Y(pic)_3(TDD)](TDD=N,N,N＇,N＇-四苯基-3,6-二氧杂辛二酰胺)的配合物.晶体结构分析表明,TDD作为四齿配体连同-pic的配位O原子形成具有一定孔径的“类环状”配位结构.Eu配合物中半径较大的中心离子处于类环孔腔平面之下;而Y配合物中半径较小的中心离子处于环内.由于pic参与配位,使配合物结构随中心离子半径的变化变得更加敏感.
The compounds of the formula [Eu (pic) _3 (TDD)] · 2CH_3CN and [Y (pic) _3 (TDD)] (TDD = N, N, N’N’-tetraphenyl- The results of crystal structure analysis show that TDD forms a “quasi-cyclic” coordination structure with a certain pore size as a tetradentate ligand along with the coordination O atom of -pic. The larger radius of the Eu complex The central ions are under the surface of the quasi-annular cavity, while the smaller central ions in the Y complex are in the ring, and the complex structure becomes more sensitive to the change of the central ion radius due to the coordination of pic.
