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。
Synthesis of o-nitrobenzenesulfonated alanine ligand 2-NBS-AlaH (1) (2-NBS-AlaH = o-nitrophenylsulfonylalanine) and manganese complexes [Mn , 4’-bipy) (H2O) 4] 2 [(4,4’-bipy) 2 (H2O) 3 (2-NBS-Ala) 4] (2). Its structure was determined by X-ray single crystal diffraction. The ligand formed a one-dimensional chain structure through hydrogen bonding. In the complex 2, 4,4’-bipy formed a one-dimensional chain structure of manganese ions. Magnetic studies show that the complexes exhibit weak ferromagnetism due to intermolecular spin coupling.
