| 摘要: 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].samcn4-,sampn4-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(NO2-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=-2JS1·S2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. |

| Abstract: New binuclcar complexes, [Cu(samcn,Ni(NO2-phen)2] and [Cu(sampn)Ni(NO2-phen)2] were synthesized, samcn4-, sampn4- and NO2-phen denote N,N'-ethylenedisalicylamidate anion, N,N'-1,2-propancdisalicylamidate anion and 5-nitro-1,10-phenanthrolinc rcspcccively. Based on IR, elemental analyses and electronic spectra the complexes arc proposed to have phcnoxy-bridgcd structure and to consist of a Cu(Ⅱ)in a planar environment and Ni(Ⅱ)in a distorted octahedron. The complexes have been characterized with variable tcmparaturc magnetic susceptibility(4-300K)and the date were the best fit to a susceptibilityequation derived from spin Hamilton, H=2JS1·S2. The exchange integral, J, was found to be -1.77cm-1 for [Cu(samcn)Ni(NO2-phen)2] and -1.74cm-1 for [Ca(sampn)Ni(NO2-phen)2], indicating that a extremely weak antifcrromagnetic spin-exchange interaction operates between the metal ions. |
