| 摘要: 合成了双吡啶酰腙Schiff碱配体（L），并采用核磁共振氢谱、质谱、红外光谱和元素分析等手段对其结构进行了表征。进一步采用溶剂挥发法合成了2个配合物{[Cd（L）2Cl2]·2DMF·6H2O}n（1）和[Hg（L）Cl2]n（2）。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，并对配合物的热稳定性及其在常温下对甲醇蒸气的吸附进行了考察。实验结果表明，2个配合物均为1D配位聚合物，配合物1对甲醇蒸气有较好的吸附能力。 |

| Abstract: A bis-pyridyhylhydrazone Schiff base ligand (L) was synthesized and characterized by 1H NMR, MS, FT-IR and elemental analysis. Two complexes, {[Cd(L)2Cl2]·2DMF·6H2O}n (1) and[Hg(L)Cl2]n (2), were synthesized from the reaction of the ligand with CdCl2 and HgCl2, respectively. The structures of the ligand and two complexes were determined via X-ray single crystal diffraction, which show that both of the two complexes have 1D-chain structures. Furthermore, the thermal stabilities and vapor adsorption for MeOH at room temperature were investigated. The results demonstrate that complex 2 has a better thermal stability than complex 1, while complex 1 has a better adsorption for MeOH because of its pore structures. |
