Nickel metal coordination polymer and preparation method thereof

A nickel metal coordination polymer disclosed in the invention has a three-dimensional porous supramolecular network structure, and has a chemical formula of {[Ni(ppda)(mbib)].H2O}n, wherein ppda represents terephthalic acid, and bib represents 1,3-bis(1-imidazolyl)benzene. The coordination polymer belongs to the orthorhombic system, and the space group is Pna21. The carboxyl groups of p-phenylenediacetic acid and metal Ni are bridged in a "V" form to form a one-dimensional ring, the adjacent one-dimensional rings are combined by a hydrogen bond to form a two-dimensional supramolecular layer,and the three-dimensional porous supramolecular network structure is formed through the pi-pi action between phenyl rings of the 1,3-bis(1-imidazolyl)benzene ligand, so a certain foundation is laid for the electrochemical expansion of the Ni coordination polymer. A preparation method of the nickel metal coordination polymer adopts hydrothermal synthesis. The preparation method has the advantages of simplicity in operation
