摘要
采用水热法合成了二聚体Mn(Ⅱ)配合物[Mn(1,6-nds)(phen)2(H2O)]2·(CH3OH)3·(H2O)2,(1,6-nds=1,6-萘二磺酸根离子,phen=1,10-邻菲罗啉)。采用X射线单晶衍射、红外光谱、热重分析和紫外可见光谱等方法对配合物进行了表征。X射线单晶衍射表征结果表明,该配合物晶体属于三斜晶系,空间群为P-1。锰离子与两个1,10-邻菲罗啉分子、一个水分子和1,6-萘二磺酸根离子配位,形成[Mn(1,6-nds)(phen)2(H2O)]结构单元。这种结构单元、未配位的甲醇和水分子通过两种类型的氢键O-H…O和O-H…S相连,形成三维网状结构。与配体相比,配合物的荧光光谱发生红移,其最大发射峰在439 nm。
The dimeric Mn(Ⅱ) complex [ Mn( 1,6-nds) ( phen)2 (H2O) ]2·( CH3OH)3·(H2O)2, ( 1,6-nds = 1,6-naphthalene-disulfonate anion, phen = 1, 10-phenanthroline ) was synthesized by hydrothermal method. It was characterized by X-ray crystal diffraction, IR, thermogravimetric analysis, UV-Vis spectroscopy, etc. The characterization results of X-ray single crystal diffraction show that the crystal of the complex crystallized in triclinic system with space group P-1. The manganese anion coordinates with two 1, 10-phenanthroline molecules, one water molecule and 1, 6-naphthalene- disulfonate anion to form [Mn (1,6-nds) (phen)2 (H2O) ] structural unit. The structural units, methanol and water molecules are interconnected through two kinds of hydrogen bonds O-H ... O and O-H ... S, forming a three-dimensional network structure. Compared with the ligands, the fluorescence spectrum happens red shift, and the maximum emission peak is at 439 nm.
