二羟基苯二磺酸锰配合物的合成、晶体结构及热稳定性

Synthesis, Crystal Structure and Thermal Stability Property of Dihydroxybenzene Disulfonic Acid Manganese(Ⅱ) Complex

在水溶剂中,采用回流法合成了两个二羟基苯二磺酸单核Mn(Ⅱ)含氮配体配合物Na[Mn(3,5-(SO3)2HCat)(phen)2H2O](1)和[Mn(3,5-(SO3)2H2Cat)(phen)2H2O]·H2O(2)(H2Cat=1,2-二羟基苯,phen=1,10-邻菲罗啉)。采用X射线单晶衍射、红外光谱、元素分析、紫外可见光谱和热重分析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:两个配合物晶体均属于单斜晶系,晶族分别为P2(1)/c和P2(1)/n。两个配合物的配位方式相似,锰离子均与两个1,10-邻菲罗啉、一个水分子以及磺酸基配位。锰离子是六配位的。

The two mononuclear containing N-donor ligand Mn（Ⅱ） complexes Na[Mn（3,5-（SO3）2HCat）（phen）2H2O] （1） and [Mn（3,5-（SO3）2H2Cat） （phen）2H2O]·H2O （2） （H2Cat=1,2-dihydroxybenzene,phen=1,10-phenanthroline） were synthesized by reflux method in water.The two complexes were characterized by X-ray crystal diffraction,IR,elemental analysis methods,UV-Vis spectroscopy and thermogravimetric analysis,etc.The characterization results of X-ray single crystal diffraction showed that the crystal of the complexes were crystallized in monoclinic system with the space groups P2 （1）/c and P2 （1）/n,respectively.The manganese ions in the two coordination compounds had similar coordination mode,and coordinated with two 1,10-phenanthroline molecules,a water molecule and sulfonic acid group.The manganese ion was hexa-coordination.
