本文合成了两个新的双核配合物, [Cu(sampu)Ni(L)2], sampn^4^-表示N,N'-1,2-丙二水杨酰胺阴离子, L表示2,2-联吡啶(bpy)或1,10-菲咯啉(phen),经元素分析, IR和电子光谱等方法已推定配合物具有酚氧桥结构和Cu(II)及Ni(II)的配位环境分别为平面四方及八面体构型, 配合物的变温磁化率已测(4-300K), 其数值用最小二乘法和从自旋哈密顿算符H=-2JS1S2导出的磁方程拟合, 求得交换参数为J=-1.90cm^-^1(pby)和J=1.68cm^-^1(phen), 表明两个Cu(II)-Ni(II)双核配合物中有弱的反铁磁自旋交换相互作用。

Cu(sampn)NiL2 were synthesized (H4sampn = N, N'-1,2-propanedisalicylamide; L = 2,2'-bipyridyl, 1,10-phenanthroline). Based on elemental analyses, IR, and electronic spectra, the complexes probably have PhO-bridged structure and consist of Cu(II) in a planar environment and Ni(II) in a distorted octahedron. The complexes were characterized with variable-temp. magnetic susceptibility (4-300 K) and the data are least-squares fit to a susceptibility equation derived from spin Hamilton, H = 2JS1S2. The exchange integral, J, is -1.90 (bpy) and -1.68 (phen) cm-1 indicating that weak antiferromagnetic spin exchange interaction operates between both metal ions.
