摘　　要：使用K3[Fe(CN)6]提供氰基阴离子和Fe2+阳离子,与Ni(Ac)2·4H2O和2,2’–联吡啶(2,2’–bpy)在水热条件下反应制备了氰基桥连的双金属铁镍配合物[Fe(2,2’–bpy)2Ni(CN)4]n(1),用红外光谱、热重分析和X射线衍射对其进行表征。结果表明:在配合物1中,[Fe(2,2’–bpy)2]2+阳离子和[Ni(CN)4]2–阴离子通过氰基桥联形成Fe2+、Ni2+离子交替存在的一维锯齿链[Fe(2,2’–bpy)2Ni(CN)4]n,热重分析显示,双金属配合物[Fe(2,2’–bpy)2Ni(CN)4]n有较好的热稳定性,磁性测量表明,配合物[Fe(2,2’–bpy)2Ni(CN)4]n中金属铁镍离子间存在强的反铁磁相互作用。A complex[Fe(2,2’–bpy)2Ni(CN)4]n(1)was synthesized with K3[Fe(CN)6]as a source of cyanide anions and Fe2+cations,2,2’–bipyridine(2,2’–bpy)and Ni(Ac)2·4H2O under hydrothermal condition.Based on the X-ray crystallographic studies,two cations Fe2+and Ni2+are alternately bridged by some cyanide ligands to form a 1D zigzag chain with 2,2’–bpy terminal ligands in complex 1.The thermogravimetric analysis shows that a bimetallic complex[Fe(2,2’–bpy)2Ni(CN)4]n has a good thermal stability.The magnetic measurement reveals an intense antiferromagnetic interaction between iron and nickel ions in complex 1.
