Problems solved by technology

The above mixed metal complexes are generally constructed by a single organic ligand, but mixed metal complexes constructed by mixed organic ligands have rarely been reported.
Designing and synthesizing such metal-mixed coordination polymers based on mixed organic ligands is a great challenge, because there are competing reactions between different ligands and metal ions in this system, resulting in products often containing only one Ligands, not the envisioned mixed-ligand-mixed-metal coordination polymers

Embodiment 1

[0044] Trimellitic acid (0.5mmol, 105.1mg), 1,2,4-triazole (0.2mmol, 13.8mg), ammonium formate (0.2mmol, 12.6mg), lithium carbonate (0.1mmol, 7.4mg), Copper nitrate (0.4mmol, 96.6mg) and cobalt nitrate (0.4mmol, 116.4mg) were dissolved in water (6mL), and sealed in a 25mL hydrothermal reaction kettle. Then heat the reaction mixture at 10°C per hour to 160°C, maintain this temperature for 3 days, and then lower it to room temperature to obtain purple columnar crystals, which are the target product Cu(II)-Co(II) mixed metal coordination polymerization The yield is about 51%. The main infrared absorption peaks of the target product are: 3602w, 1705m, 1613s, 1566s, 1442s, 1388vs, 1268w, 1168w, 1098m, 1005w, 884w, 750m, 666m, 539w, 448w.

Embodiment 2

[0046] Trimellitic acid (0.3mmol, 63.0mg), 1,2,4-triazole (0.06mmol, 4.1mg), ammonium formate (0.06mmol, 3.8mg), lithium carbonate (0.06mmol, 4.4mg), Copper nitrate (0.24mmol, 58.0mg) and cobalt nitrate (0.24mmol, 70.0mg) were dissolved in water (6mL), and sealed in a 25mL hydrothermal reaction kettle. Then the reaction mixture was heated at 10°C per hour to 140°C, maintained at this temperature for 3 days, and then lowered to room temperature to obtain purple columnar crystals, the target product, with a yield of about 42%. The main infrared absorption peaks of the target product are: 3600w, 1703m, 1610s, 1562s, 1440s, 1385vs, 1262w, 1163w, 1092m, 998w, 880w, 743m, 662m, 531w, 442w.
