摘要: 合成了Schiff碱配体3-乙酰吡啶缩邻氨基苯甲酰腙(L1)及4-乙酰吡啶缩邻氨基苯甲酰腙(L2),并分别与HgCl2进行了配位反应,得到2个配位聚合物{[Hg(L1)Cl2]·CH3OH}n(1)和[Hg(L2)Cl2]n(2),采用1H NMR、FTIR和元素分析等手段对化合物进行了表征,并对配合物的热稳定性进行了考察。通过X射线单晶体衍射技术测定了2个配合物的单晶结构,结构解析表明,配合物1属于三斜晶系,P1空间群,配合物2属于单斜晶系,P21/n空间群。 |

Abstract: Two complexes {[Hg(L1)Cl2]·CH3OH}n (1) and [Hg(L2)Cl2]n (2) were synthesized from the reaction of Schiff base ligand 3-acetylpyridine-o-aminobenzoylhydrazone (L1) and ligand 4-acetylpyridine-o-aminobenzoylhy-drazone (L2) with HgCl2, respectively. The compounds are characterized by 1H NMR, FTIR, and elemental analysis, and their structures are measured via single crystal X-ray diffraction. The results show that the complex 1 crystallize in triclinic system, space group P1; the complex 2 crystallize in monoclinic system, space group P21/n. Further the thermal stabilities of the two complexes were investigated. CCDC:1496029, 1; 1496028, 2. |
