摘　　要：叠氮桥联配合物具有结构和磁性质多样性的特点,在分子磁学和功能材料的研究中具有重要的理论意义和潜在的应用前景。结合文献和我们的工作,本文简述了目前叠氮桥联配合物的结构和磁性,并对其研究方向进行了展望。Azido-bridged metal complexes have received much attention in the field of molecular-based magnetic materials because of their remarkable structural diversity and rich magnetic behavior. The azido-bridged copper（Ⅱ）, manganese（Ⅱ）, nickel（Ⅱ） and cobalt（Ⅱ） complexes have been studied extensively, and various structural and magnetic properties have been investigated. The azido anion is a versatile ligand which can link transition metal ions in different coordination modes. It has been widely accepted that the exchange is, with some exceptions, generally ferromagnetic in nature for the end-on （μ-1,1, EO） mode, and antiferromagnetic for the end-to-end （μ-1,3, EE） mode. In addition, the exchange between the transition metal ions is usually dependent upon the coordination geometries of the metal ions. Based on the literatures and our work, the structure and magnetism of azido-bridged complexes are generally presented. The perspective for future development in this field is also briefly mentioned.
