Embodiment

[0017] Synthesis of high-nuclear zinc clusters based on sulfur-containing triazole ligands:

[0018] Weigh 0.2mmol (0.0294g) H 3 L, 0.2mmol (0.0745g) Zn(ClO 4 ) 2 ·6H 2 O,0.2mmol(0.0617g)Cd(NO 3 ) 2 4H 2 O was mixed in 10 mL of DMF, and the obtained mixture was stirred and reacted for 6 h at room temperature, and then filtered to obtain a colorless solution. The filtrate was allowed to stand for slow volatilization, and after 25 days, colorless cubic crystals were precipitated from the mother liquor, separated, washed, and dried.

[0019] see figure 1 In the molecular structure diagram of the zinc cluster compound of the present invention, for the convenience of observation, the peripheral guest solvent molecules are deleted. It can be clearly observed from the figure that the zinc cluster compound of the present invention is a 24-nuclear double-layer ring cluster compound composed of twenty-four zinc ions, twenty-four ligands and six coordinated water molecules, Ther...

Abstract

The invention discloses a high-nuclear zinc cluster compound based on a sulfur-containing triazole ligand and a preparation method thereof. According to the molecular structural graph, the high-nuclear zinc cluster compound is the 3-thioketone-5-mercapto methyl-1,2,4-triazole 24-nuclear zinc cluster compound. In the preparation process, by the adoption of the method of adding the second kind of metal salt cadmium nitrate, the solubleness of the indissolvable sulfur-containing triazole cluster compound is improved; the zinc cluster compound has the potential application value in the aspects of modern medicine, optics, magnetics, and ion selective absorption and separation. The method has the wide application prospect in the aspect of preparation of indissolvable cluster compound monocrystals.

Description

technical field [0001] The invention relates to a synthesis method of a complex, in particular to a preparation method of an insoluble cluster single crystal, in particular to a high-nuclear zinc cluster compound based on a sulfur-containing triazole ligand and a preparation method thereof. technical background [0002] There are many kinds of triazole derivatives, and as important functional groups, triazole ligands have relatively strong ability to complex metal ions and form hydrogen bonds, so they have attracted the attention of many researchers in the field of chemistry. In biological systems, because sulfur-containing compounds exist around the metal center of metalloproteases, they have potential application value in disease treatment. They can be used as raw materials for metalloproteases in medicinal chemistry, and can also be used as synthetic semiconductors in material chemistry. The raw material of the material is widely used. In the synthesis of complexes, the ...
