Embodiment 1

[0023] Weigh CoCl 2 ·6H 2 O (0.238g, 1.0mmol), 5-nitroorotic acid (0.201g, 1.0mmol), 1,3-two (4-pyridine) propane (0.198g, 1.0mmol) were placed in a round bottom flask, and Distilled water 10mL, ethanol 5.0mL and DMF 1.0mL, stirred at room temperature for 10min, then transferred the mixture to a stainless steel reactor at 130°C for 48h, cooled naturally to room temperature, separated by filtration to obtain red blocky crystals.

Embodiment 2

[0025] Weigh Co(OAc) 2 4H 2 O (0.249g, 1.0mmol), 5-nitroorotic acid (0.201g, 1.0mmol), 1,3-two (4-pyridine) propane (0.198g, 1.0mmol) were placed in a round bottom flask, and Distilled water 10mL, ethanol 5.0mL and DMF 1.0mL, stirred at room temperature for 10min, then transferred the mixture to a stainless steel reactor at 160°C for 24h, cooled naturally to room temperature, separated by filtration to obtain red blocky crystals.

Embodiment 3

[0027] Weigh Co(NO 3 ) 2 ·6H 2 O (0.291g, 1.0mmol), 5-nitroorotic acid (0.201g, 1.0mmol), 1,3-bis(4-pyridine)propane (0.198g, 1.0mmol) were placed in a round bottom flask, added 15mL of distilled water, 7.5mL of ethanol and 1.5mL of DMF were stirred at room temperature for 10min, then the mixture was transferred to a stainless steel reactor at 140°C for 36h, cooled naturally to room temperature, separated by filtration to obtain red blocky crystals.

[0028] The red blocky crystals prepared in the above examples were subjected to X-ray single crystal diffraction test and analysis. It was determined that the occupancy ratios of cobalt ions, ligands and coordination water were all 0.5, and its asymmetric structural unit was composed of 0.5 cobalt ions , 0.5 5-nitroorotate, 0.5 1,3-bis(4-pyridine) propane, and 0.5 coordinated water molecules. The simplified structure is [Co 0.5 (HL) 0.5 (bpp) 0.5 (H 2 O) 0.5 ], the crystal system is triclinic, the space group is P-1, and t...

Description

technical field [0001] The invention belongs to the field of coordination chemistry, and specifically relates to a cobalt 5-nitroorotate complex, a preparation method and application thereof. Background technique [0002] Complexes generally refer to a class of compounds formed by atoms or ions of transition metals and ligand molecules containing lone pairs of electrons through coordination bonds. Complexes are a relatively large subcategory of compounds. They are widely used in daily life, industrial production and life sciences. They have developed particularly rapidly in recent years. They are not only related to inorganic compounds and organometallic compounds, but also to modern chemical compounds. The cutting-edge cluster chemistry, coordination catalysis and molecular biology are closely connected or overlapped. People have been in contact with coordination compounds for a long time, most of which are used in daily life, and the raw materials are basically obtained f...
