摘要
以2-甲基苯甲酸、邻菲罗啉和Co(ClO4)2·6H2O为原料,常温下在乙醇水溶液中合成得到了一个中心对称的双核钴的配合物[Co2(phen)4(C8H7O2)2](ClO4)2·2EtOH,用元素分析、红外光谱、热重分析和X-射线单晶衍射表征了配合物的结构。结果表明:配合物属于单斜晶系,P-1空间群,晶胞参数:a=9.684(2),b=13.077(3),c=13.958(3),α=111.11(3)°,β=94.54(3)°,γ=102.60(3)°,V=1 584.9(9)3,Z=1,μ=0.682 mm-1,F(000)=722.0,D c=1.467g·cm-3。配合物结构单元中,中心对称的双核钴[Co2(phen)4(C8H7O2)2]2+阳离子与两个结构无序的ClO-4以静电引力相作用,两个乙醇分子则通过O—H…O氢键与配位阳离子相连。
The tide centrosymmetric binuclear cobalt com- plex, [ Co2 （ phen ） 4 （ C6H7O2 ） 2 ] Co（ ClO4 ）2· 2EtOH was syn- thesized with the reaction of 2-methyl benzoic acid, 1,10- phenanthroline and Co（ ClO4 ）2· 6H2O in ethanol solution at room temperature. The structure was confirmed by elemental analysis,lR, thermogravimetric analysis and single-crystal X- ray diffractometry. The results showed that the title complex belonged to triclinic system with P-1 space group and cell parameter：a =9. 684（2）A, b = 13. 077 （3） A,e = 13.958（3） A., ct=111.11（3）°γ =94.54（3）°,7 = 102.60（3）°,V = 1584.9（9）A3,Z--1,/.t =0.682 mm^-1,F（000） =722.0, Do = 1. 467 g·cm^-9. Within the complex unit, the centrosym- metric dinuclear [ Co2 （phen） 4 （ C8 H7O2 ） 2 ] ^2＋ cation and two disordered ClO4^- anions were linked by electrostatic attrac tion, two ethanol solvate molecules were interlinked to the complex cation via O--H…O hydrogen bonds.
