本文合成了两个新型双核配合物,[Cu(samcn)Ni(L)_2]和[Cu(sampn)Ni(L)_2].samcn~(4-),sampn~(4-)及L分别表示N,N′-乙二水杨酰胺根阴离子,N,N′-1,2-丙二水杨酰胺根阴离子和5-硝基-1,10-菲绕啉(NO_2-phcn).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),其数值已用最佳拟合方法和从自旋哈密顿算符,H=-2JS_1·S_2导出的磁方程拟合,求得交换参数为J=-1.77cm~(-1)(samcn)和J=-1.74cm~(-1)(sampn),表明两个Cu(Ⅱ)-Ni(Ⅱ)双核配合物中有很弱的反铁磁性自旋交换相互作用.
In this paper, two new binuclear complexes were synthesized, [Cu (samcn) Ni (L) _2] and [Cu (sampn) Ni (L) _2] .samcn ~ (4 -), sampn ~ (4-) Denotes N, N’-ethanedisalicylamide anion, N, N’-1,2-propanedisalicylamide anion and 5-nitro-1,10-phenanthroline (NO 2 -phcn) Elemental analysis, IR, and electron spectroscopy have been used to predict the complexes with phenolic oxygen bridges and Cu (Ⅱ) and Ni (Ⅱ) coordination planes as planar tetragonal and octahedral configurations, respectively. (4-300K). The numerical values have been fitted by the best fitting method and the magnetic equations derived from the spin Hamiltonian, H = -2JS_1 · S 2, and the exchange parameter is obtained as J = -1.77cm ~ (- 1) (samcn) and J = -1.74cm -1 (sampn), indicating that there is a weak antiferromagnetic spin exchange interaction in the two Cu (Ⅱ) -Ni (Ⅱ) binuclear complexes.
