| 摘要: 通过水热方法, 以3,5-二溴苯甲酸(3,5-HBr2BC)和吡啶(py)分别与Cd(NO3)2·4H2O和MnSO4·2H2O反应, 合成了2个具有同质异心结构的一维链状配位聚合物[M3(3,5-Br2BC)6(py)2]n (M=Cd,1;Mn,2),并对其结构、荧光和磁性质进行了研究.结构分析结果表明2个化合物属于三斜晶系, P1空间群.这些配合物具有一维链状结构, 而且这些一维链状结构通过Br…Br卤键和C-H…Br氢键作用进一步形成了三维超分子框架.配合物1在室温下能分别发出很强的绿色荧光, 配合物2中相邻锰离子间存在反铁磁相互作用. |

| Abstract: Two coordination polymers, namely [M3(3,5-Br2BC)6(py)2]n (M=Cd, 1; Mn, 2), have been constructed hydrothermally using 3,5-HBr2BC (3,5-HBr2BC=3,5-dibromobenzoic acid), py (py=pyridine), and the corresponding metal salts. Single-crystal X-ray diffraction analyses revealed that the two complexes are isostructural and crystallize in the triclinic system, space group P1 The carboxylate groups of 3,5-Br2BC- ligands bridge alternately neighboring metal ions to form a chain. Adjacent chains are assembled to a 3D supramolecular framework through Br…Br halogen bonding and C-H…Br hydrogen bond. Luminescent and magnetic properties of both compounds have also been studied.
