| 摘要: 本文以 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{[HgLCl2]?2DMF}n (1) 和{[CdL2(H2O)2]?(ClO4)2?4DMF?2H2O?2CH3OH}n (2)，采用1H NMR、MS、FTIR和元素分析等技术对化合物(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 {[HgLCl2]?2DMF}n (1) and {[CdL2(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 measured via single crystal X-ray diffraction, and the structural analysis indicated that both complexes show a one-dimensional chain structure. Further their thermal stabilities and vapor adsorptions for MeOH were investigated. |
