合成了以1,1′-双(二苯基膦)二茂铁(dppf)为双齿配体的双核配合物Pd(dppf)Cl_2,并通过红外、元素分析、热重分析.电子光谱对其进行了表征.该配合物及dppf的循环伏安研究结果给出两条可逆性较好的单电子氧化还原曲线.dppf形成配合物后,茂基氧化峰电位值显著增加.Pd(dppf)Cl_2的X-射线晶体结构表明,该配合物属单斜晶系,P2_1/n空间群.晶胞参数a=12.281(2)(?),b=16.497(2)(?).c=16.896(3)(?),β=93.6(2.6)°,Z=4,D_(?)=1.423g/cm~3.与Pd(dppe)Cl_2的晶体结构进行了比较讨论,进一步研究了配体dppf和dppe的配位性能的差别.
The binuclear complex Pd (dppf) Cl_2 with bidentate ligands of 1,1’-bis (diphenylphosphino) ferrocene (dppf) was synthesized and characterized by IR, elemental analysis and TG analysis. It was characterized by cyclic voltammetry and cyclic voltammetry of dppf.The results showed that there were two single electron redox curves with good reversibility.Pd (dppf) Cl_2 X-ray crystal structure of the complex shows that the complex belongs to the monoclinic space group P2_1 / n. The unit cell parameters a = 12.281 (2) and b = 16.497 (2) The crystal structure of Pd (dppe) Cl_2 was discussed and discussed. The dppf of the ligand dppf And dppe coordination performance differences.
