| 摘要: 以三苯甲烷-4，4’，4”-三羧酸（H3TCOPM）为主配体，以含氮二齿配体4，4’-bipyridine（4，4’-bipy）为辅助配体，与Co（NO3）2·6H2O通过溶剂热反应得到了2个配位聚合物{[Co2（α-OH-TCOPM）（OH）（H2O）4]·DMF}n（1）（α-OH-H3TCOPM=三苯甲醇-4，4’，4”-三羧酸）和{[Co3（α-OH-TCOPM）2（4，4’-bipy）3（H2O）6]·2H2O}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。 |

| Abstract: 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)6·2H2O}n (2) (4,4'-bipy=4,4'-bipyridine) were synthesized by using triphenylmethane-4,4',4"-tricarboxylic acid (H3TCOPM), Co(NO3)2·6H2O 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. |
