| 摘 要： | 合成了邻硝基苯磺酰化丙氨酸配体2-NBS-AlaH (1)(2-NBS-AlaH=邻硝基苯磺酰化丙氨酸)及其锰的配合物[Mn(4，4′-bipy)(H2O)4]2[(4，4′-bipy)2(H2O)3(2-NBS-Ala)4] (2)。通过X-射线单晶衍射测定了其结构：配体通过氢键形成了一维链状结构；配合物2中，4，4′-bipy把锰离子连成了一维链状结构。磁性研究表明，配合物由于分子间的自旋耦合呈现出弱的铁磁性。 |

| Abstract: | A ligand 2-NBS-AlaH (1) (2-NBS-AlaH=N-2-Nitrobenzenesulfonyl-L-α-alanine acid)and its ID manganese(Ⅱ)complex with 4,4'-bipy as bridging ligand,of formula[Mn(4,4'-bipy)(H2O)4]2[(4,4'-bipy)2(H2O)3(2-NBS-Ala)4]n(2)have been synthesized and characterized.Single crystal structure shows that the ligand is linked via hydrogen bonds into a 1D chain structure and the structure of the complex 2 reveals that the coordination environment around the Mn(Ⅱ)ion can be described as a slightly distorted octahedron.4,4'-bipy ligands act as a μ2-bridge and join the Mn atoms into an infinite 1D chain structure.The magnetic susceptibility measurements (2～300K)agree with a weak ferromagnetic interaction between neighboring Mn ions in the chain. |
