Abstract

The invention discloses a Cu-Nd dissimilar-metal coordination polymer and a preparation method. The chemical formula of the Cu-Nd dissimilar-metal coordination polymer is {[Nd(L1)2Cu(L2)(H2O)2].3H2O}n, the molecular formula is Cl5H15CuN6NdO15, and the molecular weight is 727.10. The preparation method comprises the following steps: (1) dissolving neodymium perchlorate hexahydrate and copper acetate in distilled water; (2) dissolving 3, 5-pyrazol dicarboxylic acid and 2-pyrazine carboxylic acid in DMF (Dimethyl Formamide); and (3) mixing the solution prepared in the step (1) and the solution prepared in the step (2), using ethidene diamine to regulate pH, filtering and drying to obtain the Cu-Nd dissimilar-metal coordination polymer, wherein L1 represents 3, 5-pyrazol dicarboxylic acid withremoval of two carboxyl hydrogen atoms and with two units of negative charges; and L2 represents 2-pyrazine carboxylic acid with removal of one carboxyl hydrogen atom. The Cu-Nd dissimilar-metal coordination polymer and the preparation method disclosed by the invention have the advantages that the process is good and the repeatability is good.
