以二水氯化铜为原料，以金刚烷胺和3，5-二盐基水杨醛为原料合成了三个新的席夫碱配体C34H36X4CuN2O2(X = Cl，BrI)。用IR、UV-Vis、元素分析、摩尔电导和单晶X-射线衍射仪对其进行了表征。单晶X射线衍射分析表明，1和2为三斜晶系，P-ī空间群。每个不对称单元由一个铜(II)离子、两个相应的去质子化Schiff碱配体和一个晶格二氯甲烷分子组成。3为单斜晶系，P21/n空间群。每个不对称单元由一个铜(II)离子和两个去质子化的碘-席夫碱配体组成。中心铜(II)离子在1-3中的四配位是由相应的席夫碱配体中的两个氮原子和两个氧原子构成的，形成扭曲的四面体构型。用循环伏安法测定了配合物的电化学性质。
Abstract Complexes 1-3, C34H36X4CuN2O2 (X = Cl, Br, I), were synthesized with copper chloride dihydrate and three new Schiff base ligands derived from amantadine and 3,5-dihalosalicylaldehydes. They were characterized by IR, UV–VIS, elemental analysis, molar conductance, and single-crystal X-ray diffraction. Single-crystal X-ray diffraction analysis reveals that 1 and 2 crystallize in the triclinic system, Pī space group. Each asymmetric unit consists of one copper(II) ion, two corresponding deprotonated Schiff base ligands and one lattice dichloromethane molecule. 3 crystallizes in the monoclinic system, P21/n space group. Each asymmetric unit consists of one copper(II) ion and two deprotonated iodo- Schiff base ligands. The tetra-coordination of the central copper(II) ion in 1-3 is constructed by two nitrogen atoms and two oxygen atoms from the corresponding Schiff base ligands, forming a distorted tetrahedral geometry. Electrochemical properties of the complexes were determined by cyclic voltammetry.
