摘　　要：本文以3-二茂铁羰基丙酸(L1)、1,1'-二茂铁二羰基-3,3'-双丙酸(L2)、2,2'-联吡啶胺(dpa)以及Zn(Ac)2·2H2O为原料合成了一个结构新颖的混配合物[Zn2(L1)2(L2)(dpa)]。X-射线单晶衍射分析表明,该配合物是一个中心对称的双核配合物,并在N-H…O氢键和C-H…O氢键的作用下形成了二维的超分子化合物。采用差示脉冲对该配合物的电化学性质进行了初步的研究。A novel mixed-ligand complex [Zn-2(L1)(2)(L2)(dpa)] (L1=3-ferrocenoylpropionic acid, L2=1,1'-ferrocenedipropionic acid, dpa=2,2'-dipyridylamine) has been synthesized by the reaction of Zn(Ac)(2).2H(2)O with L1, L2 and dpa and characterized by X-ray single crystal diffraction. The results reveal that it is a centrosymmetric binuclear complex. The hydrogen bonds N-H...O and C-H...0 connect [Zn-2(L1)(2)(L2)(dpa)] units into a supramolecular of 2-D structure. In addition, the electrochemical character of the complex was investigated by differential pulse volt-metric techniques.
