双吡啶酰腙Schiff碱Hg(Ⅱ)/Cd(Ⅱ)配合物的合成及其对甲醇蒸气的吸附

Synthesis and Methanol Vapor Adsorption of Hg(Ⅱ)/Cd(Ⅱ)Complexes Derived from a Bis-pyridylhydrazone Schiff Base

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。

A bis-pyridyhylhydrazone Schiff base ligand(L)was synthesized and characterized by1 H NMR,MS,FT-IR and elemental analysis.Two complexes,{[Cd(L)2 Cl2]·2 DMF·6 H2O}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 1 D-chain struc-tures.Furthermore,the thermal stabilities and vapor adsorption for MeOH at room temperature were investigated.The results demonstrate that complex2 has a better thermal stability than complex1,while complex1 has a better adsorption for MeOH because of its pore structures.CCDC:1975243,L;1975244,1;1975245,2.
