摘 要: 以H4L1(H4L1=5-(bis-carboxymethyl-amino)-isophthalic acid)为有机配体,在水热条件下成功合成一例配位聚合物[Mn3(L2)2(H2O)6]•H2O(1)(H3L2 = 5-carboxyamino-isophthalic acid,配体H3L2由H4L1脱羧而得),并对其进行元素分析、红外光谱(infrared spectroscopy,IR)、X射线衍射(X-ray diffraction,XRD)、热重分析(thermogravimetric analysis,TGA)等表征。结构分析表明,1属于单斜晶系,C2/c空间群,是由Mn2簇与有机配体、Mn原子构筑而成的2D层状结构,相邻的层状结构之间通过氢键作用形成一个3D的超分子结构。
关 键 词: 配位化学;配位聚合物;氢键;超分子;水热合成

Abstract: A novel complex [Mn3(L2)2(H2O)6]•H2O (1) (H3L2 = 5-carboxyamino-isophthalic acid, H3L2 is obtained by decarboxylation of H4L1) was hydrothermally synthesized using H4L1 [H4L1=5-(bis- carboxymethyl-amino)-isophthalic acid] as organic ligand and characterized by X-ray single crystal structure analysis, elemental analysis, infrared spectroscopy (IR), X-ray diffraction (XRD), thermogravimetric analysis (TGA). Complex 1 is of monoclinic, space group C2/c. The structural analysis results showed that a 2D layer is constructed by the assembly of Mn2 clusters, organic ligands, and Mn atoms, meanwhile, a 3D supramolecular structure is formed through hydrogen bonding between the adjacent layers.
Key words: coordination chemistry; coordination polymer; hydrogen bond; supramolecular; solvothermal synthesis
