摘　　要：在水热条件下以K3[Fe(CN)6]作为氰根阴离子,Ni2+作为金属阳离子以及2,2'-联吡啶(2,2'-bpy)为配体制备了金属镍配合物[Ni2(CN)4(2,2'-bpy)]n(1),并用X-射线晶体衍射仪测定了其晶体结构。结果表明:在配合物1中[Ni(CN)4]2-阴离子和[Ni(2,2'-bpy)]2+阳离子通过氰基交替链接成2-D层状结构,磁性测量表明配合物中镍离子间存在反铁磁相互作用。The complex[Ni 2(CN)4(2,2′-bpy)]n(1)have been synthesized based on obtained from K 3[Fe(CN)6]as a source of anions,metal Ni 2+cations,and 2,2′-bipyridine(2,2′-bpy)ligand under hydrothermal condition.The X-ray crystallographic studies suggested that the ations[Ni(CN)4]2-and cations[Ni(2,2′-bpy)]2+are alternately bridged by the cyanide ligands to form a 2D layer with 2,2′-bpy terminal ligands in complex 1.Intramolecular antiferromagnetic interactions were observed in complex 1.
