中文摘要：
合成了一个三乙四胺六乙酸双金属配合物Ni2Co（TTHA）·12H2O（TTHA为三乙四胺六乙酸），通过X-射线衍射测得其晶体结构．该配合物属三斜晶系，Pi空间群，晶胞参数a=0．7316（2）nm，b=0．8624（2）nm，c=1．5041（4）nm；a=73．38（2），β=83．97（2），γ=70．50（2）°．每个Ni^2＋与三乙四胺六乙酸的两个氮原子和三个羧酸根上的三个氧原子以及一个配位水分子配位构成八面体构型；另有一个Co^2＋与六个水配位，最后通过氢键将整个体系连接成为三维结构．该配合物的变温磁性测量表明螯合单元中Ni（Ⅱ）间存在着很强的反铁磁相互作用，拟合结果JNi=Ni=-141．64cm^-1，gNi-2．21，Co（Ⅱ）离子的自旋轨道偶合常数λ=-134．8cm^-1。
英文摘要：
Abstract： The bimetallic complex of Ni2Co （TTHA） 12H2O （TTHA = triethylenetetraminehexaacetate） was synthesized and characterized structurally and magnetic measurement. It crystallizes in the triclinic space group P i with a=0. 731 6（2） nm, b=0. 862 4（2） nm, c= 1. 504 1 （4） nm; a=73.38（2）, β= 83.97（2）, γ= 70. 50（2）°. The crystal structure is built up of discrete [Ni2（TTHA）（H2O）2]^2-, Co（H2O）6^2＋ and water molecules. The result of the variable magnetic measurement shows that there is strong antiferromagnetic interaction between each two Ni（Ⅱ） ions, with JNi-Ni=-141. 64 cm^-1, gNi=2. 21 and the constant of spinorbit coupling of Co（Ⅱ） λ=-134. 8 cm^-1.
