Abstract

The invention relates to a terbium-tungsten multi-metal complex containing tri(2-methyl pyridine)amine ligand and a preparation method thereof. The synthetic scheme includes: preparing the ligand trimethyl pyridylamine and TbCl3.6H2O into an anhydrous methanol solution respectively, conducting mixing under room temperature stirring, performing stirring for 2h, then carrying out fltering, placing a filtrate loaded beaker into an isopropyl ether holding container, and employing gas-liquid interface diffusion process to obtain a Tb(tpma)Cl3 complex, then preparing Tb(tpma)Cl3 and K3[W(CN)8] into aqueous solutions respectively, conducting mixing under room temperature stirring, performing stirring for 2h, standing the filtrate in the air to volatilize slowly, thus obtaining the target product about two weeks later.

Example Embodiment

[0010] Example 1 Synthesis of complex:

[0011] Add 0.1mmol of TbCl 3 ·6H 2 O (0.0374g) and 0.1mmol of tpma (0.029g) were dissolved in 5ml of anhydrous methanol, mixed the above two solutions, stirred at room temperature for 2 hours, filtered, and put the beaker with the filtrate into the isopropyl ether In the container, Tb(tpma)Cl is obtained by gas-liquid interface diffusion method 3 Complexes. Then 0.1mmol of Tb(tpma)Cl 3 (0.0555g) and 0.1mmolK 3 [W(CN) 8 ](0.05lg) is configured as an aqueous solution, stirred at room temperature for 2h and then filtered. The filtrate is allowed to stand in the air and volatilize slowly. The target product can be obtained in about two weeks. The calculated yield is 32% based on the metal Tb element content.

Example Embodiment
