本文合成了四个新型双核配合物、[Cu(samen)Fe(L)Cl]和[Cu(sampn)Fe(L)Cl]。经元素分析、IR, 电导、磁性测量等手段推定配合物具有酚氧桥结构, Cu(II)及Fe(III)的配位环境分别为平面四方及四角锥的构型, Fe(III)离子的自旋态S=3/2。测定了配合物[Cu(samen)Fe(L)Cl]的变温磁化率(4-300K), 参数J和θ值表明两个双核配合物中金属离子之间有中等程度的反铁磁性超交换作用和双核单元之间有弱的分子间相互作用。

2,2'-bipyridine (bpy), 1,10-phenanthroline (phen)) and [Cu(sampn)Fe(L)Cl] (H4sampn = N,N'-2-propanedisalicylamide) were synthesized. From elemental analyses, IR, magnetic and conductance measurements, the complexes have phenoxy-bridged structure and consist of a Cu(II) in a planar environment and Fe(III) in a square-pyramidal environment with S = 3/2. [Cu(samen)Fe(L)Cl] were characterized with variable-temp. magnetic susceptibility (4-300 K), giving the parameters J = -23.12 cm-1, q = -4.1 K for bpy and J = -40.77 cm-1, q = -4.6 K for phen, indicating that a moderate antiferromagnetic spin-exchange interaction operates between the metal ions and only a weak intermol. interaction is present between 2 binuclear units.
