摘要
以三苯甲烷-4,4′,4″-三羧酸(H_3TCOPM)为主配体,以含氮二齿配体4,4′-bipyridine(4,4′-bipy)为辅助配体,与Co(NO_3)_2·6H_2O通过溶剂热反应得到了2个配位聚合物{[Co_2(α-OH-TCOPM)(OH)(H_2O)_4]·DMF}_n(1)(α-OH-H_3TCOPM=三苯甲醇-4,4′,4″-三羧酸)和{[Co_3(α-OH-TCOPM)_2(4,4′-bipy)_3(H_2O)_6]·2H_2O}_n(2)。晶体结构分析表明,配合物1为四边形的二维层状结构,而配合物2为二维网状结构。采用红外光谱、粉末X射线衍射对配合物进行了表征,用热重分析仪研究了其热稳定性。
Two new coordination polymers {[Co2（α-OH-TCOPM）（OH）（H2O）4]DMF}n （1） （α-OH-H3TCOPM=tris（p-carboxyphenyl）methanol） and {Co3（α-OH-TCOPM）2（4,4＇-bipy）3（H2O）62H2O}n （2） （4,4＇-bipy=4,4＇-bipyridine） were synthesized by using triphenylmethane-4,4＇,4＂-tricarboxylic acid （H3TCOPM）, Co（NO3）26H2O and N-donor ligands （4,4＇-bipy） through the solvothermal reaction. X-ray crystallography analysis reveals that 1 exhibited a quadrilateral 2D layered structure, while 2 showed a 2D net structure. Both complexes were also characterized by infrared spectra and powder X-ray diffraction, and their thermal stabilities were studied.
