摘　　要：采用高效微波法合成了邻羧基苯甲酰二茂铁酸锶配合物,通过元素分析、红外光谱分析、热重分析以及X-射线单晶衍射分析对其进行结构表征,并利用循环伏安法研究了此配合物在pH为7.0时的电化学性质。X-射线单晶研究表明,标题配合物分子式为[Sr(FcCOC6H4COO)2(H2O)2],属斜方晶系、Pccn空间群。在ac和ab平面上呈现以金属为节点的船式交替一维链构型,并通过氢键和π-π堆积作用进一步自组装成二维层状结构以及三维网络。循环伏安法结果表明,该配合物在pH为7.0时为准可逆氧化还原过程,可作为新型电化学材料进行应用。A new srontium complex based on O-ferrocecarbonyl benzoic acid ligand was synthesized by high-efficiency microwave synthesis.The structure was characterized by elemental analysis,thermal gravity-differential thermal gravity analysis（TGDTG）,infrared spectroscopy（IR）and single-crystal X-ray diffraction.In addition,the electrochemical property of the compound in pH 7has been studied by cyclic voltammetry.The crystal structure analysis demonstrates that the molecular formula for the title compound is[Sr（FcCOC6H4COO）2（H2O）2].Crystal system and space group is orthorhombic and Pccn,respectively.The complex exhibits the one dimensional metal-node-based chains with the unique feature of boat-like configurations appearing alternatively in ac plane and ab plane.With the help of hydrogen bond andπ-πstacking,the adjacent one dimensional chains are selfassembled to the two dimensional layers,further to form the three dimensional framework.The result of cyclic voltammetry test indicates that the complex shows quasi-reversible redox wave in pH 7.0,which reveals that this compound may be a potential electrochemical material.
