| 摘要: 以2，2'-二氨基二苯醚和4-吡啶异氰酸酯反应合成了含吡啶二脲配体（L），并分别与HgCl2和Cd（ClO4）2进行了配位反应，得到2个配位聚合物{[Hg（L） Cl2]·2DMF}n（1）和{[Cd（L）2（H2O）2]（ClO4）2·4DMF·2H2O·2CH3OH}n（2），采用1H NMR、MS、FTIR和元素分析等对化合物L进行了表征。通过X射线单晶衍射技术测定了配体及2个配合物的单晶结构，结构解析表明，2个配合物均为一维链状结构。进一步考察了2个配合物的热稳定性及其对甲醇蒸气的吸附性能。 | |

| Abstract: A bis(pyridylurea) ligand(L) was synthesized from the reaction of bis(2-aminophenyl) ether with 4-isocyanatopyridine. HgCl2 and Cd(ClO4)2 reacted with L to give two coordination polymers {[Hg(L)Cl2]·2DMF}n (1) and {[Cd(L)2(H2O)2](ClO4)2·4DMF·2H2O·2CH3OH}n (2), respectively. The ligand was characterized by 1H NMR, MS, FTIR, and elemental analysis. The structures of the ligand and two complexes were analyzed via single crystal X-ray diffraction, and the structural analysis indicated that both complexes show a one-dimensional chain structure. Their thermal stabilities and vapor adsorptions for MeOH were further investigated. | |
