摘要: 采用水热法合成单核钴配合物[Co(H2L)(phen)2(H2O)]·4H2O(H2L2-=邻羟基苯⁃1,3⁃二磺酸根离子,phen=1,10⁃邻菲罗啉)。通过单晶X射线衍射、元素分析、热重分析等对配合物进行结构和组成表征。单晶衍射研究表明,配合物中Co2+是六配位,与2个phen配体的4个氮原子以及水分子和磺酸基氧原子配位,形成扭曲的八面体配位构型。配合物的荧光发射峰与配体相比发生了蓝移,最大发射峰在380 nm。

Abstract: A mononuclear cobalt complex [Co(H2L)(phen)2(H2O)]·4H2O (H2L2-=4,5⁃dihydroxy⁃1,3⁃disulfonate ion, phen=1,10⁃phenanthroline) was synthesized by hydrothermal method. The composition and structure of the complex were characterized by X ray single crystal diffraction, elemental analysis and thermogravimetric analysis. Single crystal diffraction study shows that the cobalt ion is six⁃coordinated, which can coordinate with the four nitrogen atoms of two phen ligands and the oxygen atoms of water molecule and sulfonate group, forming the twisted octahedral configuration in the complex. Compared with the ligand, the fluorescence emission peak of the complex has a blue shift, and the maximum emission peak is at 380 nm.

Key words: Fluorescence property, Cobalt ion, Mononuclear, Crystal structure
