Embodiment 1

[0041] 0.5g H 6 TTHA, 0.8g 4,4′-bipyridine and 0.6g Mn(CH 3 COO) 2 4H 2 O was added to 40 mL of deionized water. Then place it in an autoclave at 120° C. for 48 hours at a constant temperature. After cooling to room temperature, crystals are precipitated, and the crystals are washed with deionized water for several times to obtain a manganese complex. The manganese complex is light yellow needle crystal. Elemental analysis data C 60 h 74 N 18 o 37 mn 6 , Theoretical: C, 36.60; H, 3.79; N, 12.81%. Found: C, 36.27; H, 3.41; N, 13.25%. Main infrared data (KBr, cm -1 ): 3268(s); 2979(s); 1712(s); 1594(s); 1487(w); 1303(w).

[0042] Analyze the single crystal structure of the manganese complex prepared in Example 1 of the present invention, collect the single crystal diffraction data with a Bruker Smart CCD diffractometer, and use a graphite monochromator to monochromatize Mo / kα rays Scan, obtain following result: the manganese complex that the embodiment of the pre...

Embodiment 2

[0044] 0.5g H 6 TTHA, 0.8g 4,4′-bipyridine and 0.6g Mn(CH 3 COO) 2 4H 2 O was added to 40 mL of deionized water. Then place it in an autoclave at 140° C. for 72 hours at a constant temperature. After cooling down to room temperature, crystals are precipitated, and the crystals are washed with deionized water for several times to obtain a manganese complex.

[0045] The manganese complex prepared in Example 2 of the present invention was analyzed by X-ray diffraction, and its diffraction peaks were consistent with the simulated diffraction peaks obtained by single crystal analysis in Example 1 of the invention, as shown in image 3 shown. It shows that the same substance is obtained according to the preparation methods of Example 1 and Example 2.

Abstract

The invention relates to a manganese complex with anti-ferromagnetism and a preparation method and application thereof. A molecular formula of the manganese complex is {[Mn6(TTHA)2(4,4'-bipy)3(H2O)10].3H2O}n, wherein TTHA is a ligand 1,3,5-triazine-2,4,6-triamine-hexacetic acid(H6TTHA) of removing six protons, and 4,4'-dipyridyl is 4,4-dipyridyl molecule. The preparation method of the manganese complex comprises the step that the H6TTHA, the 4,4'-dipyridyl and Mn(CH3COO)2.4H2O are added into deionized water for a hydrothermal reaction. The preparation method of the manganese complex is simplein steps and low in cost, and the prepared manganese complex has anti-ferromagnetism.

Description

technical field [0001] The invention relates to a manganese complex, in particular to a metal ion with manganese (II) as the center, 4,4'-bipyridine and H 6 TTHA is a three-dimensional network structure complex composed of ligands. The manganese complex has anti-ferromagnetism and can be used as an anti-ferromagnetic material. It also relates to a one-step hydrothermal synthesis method of the manganese complex, which belongs to the technical field of magnetic materials. Background technique [0002] Magnetic materials have a very wide range of applications, such as permanent magnet materials for motors, iron core materials in transformers, and disks in storage, and are closely related to information technology, automation, and national defense. Magnetic metal complexes appeared late, so they are classified as molecular magnets, which are prepared by organic synthesis, complex synthesis and other methods and have a critical temperature (T C ) Molecular compounds that can be ...
