摘　　要：采用水热法合成得到了链状钴配合物[Co(4,4'-bipy)(H_2O)_4]n·2nH_2L·4nH_2O(H_2L-=2,5-二羟基苯磺酸离子,4,4'-bipy=4,4’-联吡啶)。采用X射线单晶衍射、元素分析、红外光谱、热重分析等对配合物进行了组成和结构表征。单晶衍射研究表明,配合物中钴离子与4,4'-bipy的氮原子配位和水分子的氧原子配位,形成扭曲的八面体配位构型。H_2L-配体没有配位,只是平衡结构中的电荷。在结构单元中,[Co(4,4'-bipy)(H_2O)_4]+,H_2L-和H_2O之间通过氢键相连。配合物的荧光发射峰与配体相比发生了红移,最大发射峰在411 nm。The chain cobalt complex [Co（4,4 ＇-bipy）（H2O）4]n·2 nH2L ·4 nH2O（H2L-= 2,5-dihydroxybenzene sulfonate ion,4,4＇-bipy = 4,4＇-bipyridine） was synthesized by hydrothermal method. The composition and structure of the complex were characterized by X ray single crystal diffraction,elemental analysis,infrared spectroscopy and thermogravimetric analysis. Single crystal diffraction study can show that the cobalt ion can coordinate with the nitrogen atoms of 4,4＇-bipyridine and the oxygen atoms of water molecules,forming the twisted octahedral configuration. H2L-ligands have no coordination,but only balance the charge in the structure. In the structural unit,[Co（4,4＇-bipy）（H2O）4]＋,H2L-and H2O are connected by hydrogen bonds. Compared with the ligand,the fluorescence emission peak of the complex has a red shift,and the maximum emission peak is at 411 nm.
