合成了三种异双核配合物[Cu(oxae)Co(L)(ClO4)2],其中oxae代表N,NC'-双(二氨基乙基)草酰胺二价阴离子,L代表乙二氨(en),1,3-丙二氨(pn)或1,2-丙二氨(ap)。基于红外光谱、元素分析和电子光谱,证明这些配合物具有扩展的草酰胺桥桥联结构,并且由在平面配位环境下的铜(Ⅱ)离子和八面体配位环境下的镍(Ⅱ)离子组成。同时测定了配合物的变温磁化率(4.2~300K),计算出的J值表明,配合物顺磁离子间存在反铁磁耦合。
Three kinds of heterobinuclear complexes [Cu (oxae) Co (L) (ClO4) 2] were synthesized, in which oxae represents N, NC’- bis (diaminoethyl) oxalamide dianion and L represents ethylenediamine en), 1,3-propanediamine (pn) or 1,2-propanediamine (ap). Based on the IR, elemental analysis and electronic spectra, these complexes have been confirmed to have an extended oxalic acid bridged bridging structure, which is composed of copper (Ⅱ) ions in planar coordination and nickel (Ⅱ) coordination in octahedral coordination. Ion composition. The temperature-dependent magnetic susceptibility (4.2-300K) of the complex was also determined. The calculated J value indicates that antiferromagnetic coupling exists between paramagnetic ions in the complex.
