摘要
本文以苊醌单肟(HL)为配体~[1]分别与Ni(Ⅱ)和Co(Ⅱ)离子反应,得到两个簇合物:[Ni_7L_4(OAc)_6(H_2O)_2(CH_3O)_4(Im)_2](1)与[Co_7(OH)_4L_8(OAc)_2(H_2O)_6](2)。苊醌单肟配体均采用螯合-桥连模式桥连两个金属离子。配合物1和2中的七个金属离子都处于同一平面,且每个金属离子都处于畸变八面体配位环境[2]。配合物1中七个金属原子分别被四个μ_3-OCH_3~-桥连。配合物2中的七个金属离子被四个μ_3-OH~-桥连构成近乎正六边形结构。研究了它们的磁学性质。
In this work,acenaphthenequinone monooxime was used to react with Ni(Ⅱ) or Co(Ⅱ),giving two novel clusters[Ni_7L_4(OAc)_6(H_2O)_2(CH_3O)_4(Im)_2](1) and[Co_7(OH)_4L_8(OAc)_2(H_2O)_6](2).The acenaphthenequinone monooxime ligand in two compounds bridges two metal ions in a chelating-bridging mode.All of the metal ions in1 and 2,which are six-coordinated in distorted octahedral geometries,are located nearly in one plane.The seven Ni(Ⅱ) ions in 1 are consolidated together by four μ_3-OCH_3~- ligands.However,the seven Co(Ⅱ) ions in 2 are linked by four μ_3-OH~- ions to form a hexagonal skeleton.Their magnetic properties were investigated.
