preparation example Construction
[0030] The present invention also provides a method for preparing the manganese-based complex described in the above technical scheme, comprising the following steps:
[0031] The manganese-based complex is obtained by mixing 5-aminoisophthalic acid, manganese salt, acetonitrile and water and performing hydrothermal reaction.
[0032] In the present invention, the molar ratio of the 5-aminoisophthalic acid and the manganese salt is preferably 1:2-4, more preferably 1:3. The present invention has no special limitation on the specific type of the manganese salt, and the water-soluble manganese salt well known to those skilled in the art can be used, specifically, manganese sulfate monohydrate.
[0033] In the present invention, the dosage ratio of the manganese salt, water and acetonitrile is preferably 1g:15-30mL:4-8mL, more preferably 0.169g:6mL:2mL.
[0034] In the present invention, the temperature of the hydrothermal reaction is preferably 120-160°C, more preferably 130-15...
Embodiment 1
[0043] Mix 0.09g of 5-aminoisophthalic acid, 0.169g of manganese sulfate monohydrate with water (6mL) and acetonitrile (2mL), seal it in a 25mL reaction kettle, heat it to 120°C at a rate of 10°C per hour, and maintain this temperature for 24 hours, and then naturally cooled to room temperature, light pink massive crystals can be obtained, which are washed and dried successively to obtain the target product (manganese-based complex, chemical formula: {[Mn 0.5 (AIPA)(H 2 O)]} ∞ ).
[0044] The obtained manganese-based complexes are characterized as follows:
[0045] (1) Crystal structure determination of manganese-based complexes
[0046] A single crystal with a suitable size is selected for X-ray diffraction experiment at room temperature. Diffraction data collected on a BrukerApex II X-ray single crystal diffractometer, MoKα rays monochromated with a graphite monochromator by to collect diffraction data. All data were corrected by Lp factor and empirical absorption...
