以3,5-二溴苯甲酸及吡啶构筑的一维镉(Ⅱ)和锰(Ⅱ)配位聚合物的合成、晶体结构、荧光及磁性质（英文）

Synthesis, Crystal Structures, Luminescent and Magnetic Properties of 1D Cadmium(Ⅱ)and Manganese Coordination Polymers Constructed from 3,5-Dibromobenzoic Acid and Pyridine

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Mn SO4·2H2O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。

Two coordination polymers, namely [Ma（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 trielinic system, space group P1 The earboxylate groups of 3,5-Br2BC- ligands bridge alternately neighboring metal ions to form a chain. Adjacent chains are assembled to a 3D supramoleeular framework through Br... Br halogen bonding and C-H… Br hydrogen bond. Luminescent and magnetic properties of both compounds have also been studied. CCDC： 990799, 1; 990800, 2.
