【Abstract】 A new coordination compound（ [Nd（ bpdc）（ Hsuc） ]n） has been synthesized by reaction of Nd₂O₃,2,2’-bipyridyl-3,3’-dicarboxylic acid（ H2bpdc） and succinic acid（ H2suc） hydrothermal conditions. The products are purple sheet-like crystals. This paper discusses the factors affecting the synthesis,such as the ratio of reactants,the amount of solvent,temperature and cooling rate. Ultimately the optimal synthetic conditions were determined: n( Nd³⁺) ∶ n( bpdc^2-) ∶ n( suc^2-) = 2∶ 3∶ 3,5 mL H₂O as the solvent,with reaction for 96 h at a constant temperature of 140 ℃ followed by cooling at a rate of 1 ℃/h. The coordination mode,single crystal structure and electrocatalytic properties of the materials were determined by infrared spectroscopy,single crystal X-ray diffraction and linear voltammetry（ LSV） respectively. The results show that the crystal is orthorhombic,space group Pbca,and the material has the ORR electrocatalytic activity,showing good potential for application in electrocatalysis.更多还原
