Zinc complex constructed by terephthalic acid containing trifluoromethyl side chain and 4, 4'-dipyridyl and preparation method of zinc complex

The invention discloses a zinc complex constructed by terephthalic acid containing a trifluoromethyl side chain and 4,4'-bipyridine and a preparation method of the zinc complex. According to the method, 2,5-bis(trifluoromethyl)terephthalic acid serving as a ligand and 4,4'-bipyridine serving as an auxiliary ligand react with zinc chloride in a mixed solvent of N,N-dimethylformamide and water, and the [ZnL(4,4'-bipy)(H2O)]n zinc complex is obtained. The coordination of the complex adopts a coordination mode that oxygen atoms and nitrogen atoms are chelated with Zn < 2 + > ions, and mononuclear zinc ions extend infinitely through the connection of the ligand to form a three-dimensional network-shaped crystal structure. The zinc complex belongs to a monoclinic system, the space group is P21/n, and the cell parameters are as follows: alpha = 90.00 degrees, beta = 91.635 (2) degrees, gamma = 90.00 degrees and Z = 4. The preparation method has the advantages of being simple in process, good in repeatability, enviro
