摘要

合成了四(μ-丁烷)二钌(II,III)与四氰酸酯(III) [ruiruiii (n- c3h7coo)4AuIII(CN)4]n的异金属组装配合物，并用元素分析和红外光谱对其进行了表征。单晶x射线结构分析表明，该配合物由Ru2(n-C3H7COO)4+和Au(CN)4 -单元交替排列的锯齿状链分子组成，Au(CN)4 -单元呈顺式桥接模式。磁化率数据(4.5 ~ 300 K)的温度依赖性表明，双核ruiruiii单元(S= 3/2)之间的磁相互作用小得可以忽略不计，零场分裂参数D值为60 cm-1。

Geometrical isomerism in Ru2Au heterometal assembly: cis-linking of tetracyanidoaurate to tetrakis(μ-butanoato)diruthenium

A heterometal assembled complex of tetrakis(μ-butanoato)diruthenium(II,III) and tetracyanidoaurate(III) [RuIIRuIII(n-C3H7COO)4AuIII(CN)4]n was synthesized and characterized by the elemental analysis and infrared spectroscopy. The single-crystal X-ray structure analysis revealed that the complex consists of zigzag chain molecules of alternating arrangement of the Ru2(n-C3H7COO)4+ and Au(CN)4– units with cis-bridging mode of the Au(CN)4– units. The temperature dependence of the magnetic susceptibility data (4.5—300 K) showed that the magnetic interaction between the dinuclear RuIIRuIII units (S= 3/2) is negligibly small with a zero-field splitting parameter D value of 60 cm-1.
