项目摘要
The objective of this study was to synthesize a dinucleating ligand (L) having two cyclam rings in a molecule, to make its demetallic complexes with the cofacial ring arrangement, and to use of the demetallic site. Following results have been obtained.1 We succeeded in the preparation of new dinucleating ligand (L) in which two dimethyl cyclams are connected at 6th position with ortho-xylylene group.2 With use of this ligand, we prepared new dinuclear complexes of nickel(II), zinc(II), cobalt(III), cadmium(II), ruthenium(III).3 Single crystal X-ray analyzes were carried out on three crystalline compounds. In all the structures, two cyclam rings are arranged in a face-to-face manner as expected. The two metallic sites are bridged by halide ion or carbonate ions and intermetallic separations were in the range of 5.4 - 5.8A.4 In order to construct the face-to-face structure, we put methyl groups on the cyclam skeleton on purpose. This synthetic strategy was verified by preparing a similar dinucleating ligand without methyl groups and analysing the X-ray structure of its dinickel(II) complex.5 We obtained the following results on the use of the dimetallic site.(1) Dizinc complex [Zn_2(L)]^<4+> takes up carbon dioxide spontaneously from the air to give mu-carbonato dizinc comple with the cofacial ring arrangement.(2) In the solid state, chloro-bridged dinickel(II) complex [Ni_2(mu-Cl)Cl_2(L)]^+ has a pseudo one dimensional Ni-Cl alternate linear chain structure. Among Ni(II) ions, two types of antiferromagnetic interactions operate with J=-48.2(3), J'=-11.2(3)cm^<-1>.
本研究的目的是合成一个分子中含有两个环的双核配体(L),制备具有界面环排列的非金属配合物,并利用非金属中心。1.我们成功地合成了两个二甲基环与邻二甲苯基相连的新型双核配体(L)。2.利用该配体,我们合成了镍(II)、锌(II)、钴(III)、镉(II)、钚(III)的新型双核配合物。3对三种晶体进行了单晶X射线分析。在所有结构中,如预期的那样,两个自行车环以面对面的方式排列。这两个金属中心通过卤离子或碳酸盐离子桥联,金属间距离在5.4-5.8A.4之间。4为了构建面对面的结构,我们特意在环状骨架上添加了甲基。通过制备类似的无甲基去核配体和分析其镍(II)络合物的X-射线结构,验证了这一合成策略。5我们在双金属中心的使用上得到如下结果:(1)二锌配合物[Zn_2(L)]^<;4+>;;在Ni(II)离子中,存在两种反铁磁相互作用,J=-48.2(3),J‘=-11.2(3)cm^<;-1>;
