Embodiment

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

[0018] Weigh 0.2mmol (0.0294g) H 3 L, 0.2mmol (0.0581g) Ni(NO 3 ) 2 ·6H 2 O, 0.2mmol (0.0617g) Cd(NO 3 ) 2 4H 2 O was mixed in 10mL of DMF; the mixed solution was stirred and reacted at 40°C for 6 hours, and then filtered to obtain a green solution; the filtrate was left to slowly evaporate, and green blocky crystals were precipitated from the mother liquor in about 15 days, separated, washed, and dried to obtain clusters compound with a yield of 38%.

[0019] see figure 1 In the molecular structure diagram of the high-nuclear nickel 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 there are six six-coordinated nickel ions, six five-coordinated nickel ions and twelve four-coordinated nickel ions in one cluster unit. The triazole rings in the twen...

Abstract

The invention discloses a high nuclear nickel cluster based on a sulphur-containing triazole ligand and a preparation method thereof. The high nuclear nickel cluster can be known as a 3-thioketone-5-mercaptomethyl-1,2,4-triazole 24 nuclear nickel cluster from a molecular graph thereof. A method of adding second metal salt cadmium nitrate is adopted during preparation, so that the solubility of the insoluble sulphur-containing triazole cluster is improved. The nickel cluster has potential application values in the aspects of modern medicine, optics, magnetics and selective adsorption and separation of ions, and the preparation method has broad application prospects in preparation of insoluble cluster single crystals.

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 nickel 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 also 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 complexe...
