Embodiment 1
[0038] A kind of mononuclear eutectic magnetic complex {[Tb(thd) 4 ][Tb 2 (thd) 6 (CH 3 COO)][Tmim] 2} The preparation method is specifically prepared according to the following steps:
[0039] 1. The 148.9 mg Tb(thd) 3 2H 2 O and 50.4 mg of TmimI were dissolved in 10 ml of n-pentane and stirred at room temperature for 10 minutes.
[0040] 2. Dissolve 3 mg of glacial acetic acid in 5 ml of n-pentane, slowly add it dropwise into the solution obtained in step 1, and stir and react for 10 minutes at room temperature.
[0041] 3. The reaction solution obtained in step 2 was stirred and reacted at 30°C for 60 minutes.
[0042] 4. Filter the reaction solution obtained in step 3, and slowly volatilize the filtrate at room temperature to obtain the colorless transparent rod-shaped crystals of the mononuclear eutectic magnetic complex.
[0043] The yield of the magnetic complex prepared in this example was 41.2%.
Embodiment 2
[0045] A kind of mononuclear eutectic magnetic complex of the present embodiment {[Dy(thd) 4 ][Dy 2 (thd) 6 (CH 3 COO)][Tmim] 2} The preparation method is specifically prepared according to the following steps:
[0046] 1. Add 224.7 mg Dy(thd) 3 2H 2 O and 50.4 mg of TmimI were dissolved in 10 ml of n-pentane and stirred at room temperature for 10 minutes to obtain a mixed solution.
[0047] 2. Dissolve 3 mg of glacial acetic acid in 5 ml of n-pentane, and slowly add it dropwise into the mixed solution obtained in step 1, and stir and react for 10 minutes at room temperature.
[0048] 3. The reaction solution obtained in step 2 was continuously stirred and reacted at 50° C. for 120 minutes.
[0049] 4. Filter the reaction solution obtained in step 3, and slowly volatilize the filtrate at room temperature to obtain the colorless transparent rod-shaped crystals of the mononuclear eutectic magnetic complex.
[0050] The yield of the magnetic complex prepared in this examp...
