近年来,以金属配合物为基础设计合成“分子磁体”化合物,已成为无机化学领域的热点之一。一般,先制备一种具有铁磁性的分子链或片,然后再让其以自旋平行的方式堆积成三维的铁磁性物质。金属之间往往以电子传递性好的共轭体系为桥,以保证分子内的自旋相互作用,以便进行更好的磁偶合。当然不同的金属及桥基的配搭对磁性有重要影响,同时分子本身结构也是重要因素。因此,首先合成出具有磁性的分子晶体,并给出明确的结构和一
In recent years, metal complexes based on the design and synthesis of “molecular magnet” compounds, has become one of the hot spots in the field of inorganic chemistry. In general, a ferromagnetic molecular chain or sheet is prepared and then deposited into a three-dimensional ferromagnetic substance in a spin-parallel manner. Metals are often bridged with electron-transmissive conjugate systems to ensure intramolecular spin interactions for better magnetic coupling. Of course, the matching of different metals and bridges has an important influence on magnetism, and the structure of the molecule itself is also an important factor. Therefore, first, a magnetic molecular crystal was synthesized and gave a definite structure and a
