| 摘要: 采用水热法制备了两种结构类似的金属配合物M(Ls)2(M=Cu(1),Ni(2)),其中HLs是2-乙酰基吡啶缩噻吩-2-甲酰腙Schiff碱。通过元素分析、红外光谱、紫外光谱和X射线单晶衍射对它们进行了表征,结构分析表明,Ls以烯醇式与金属配位形成畸变的八面体单核配合物,化合物的分子结构被分子间弱的相互作用所稳定。配合物1通过C-H…π作用形成二维层状结构,而配合物2则通过C-H…π作用和C-H…O与C-H…N类型氢键形成三维超分子网络。 |

| Abstract: The N'-(methyl-pyridin-2-yl-methylene)-thiophene-2-carboxylic acid hydrazide Schiff base ligand(HLs) hydrothermally reacted with Cu(Ⅱ) or Ni(Ⅱ) acetates, and yielded a pair of structurally similar complexes with general formula M(Ls)2 (M=Cu(Ⅱ), 1; Ni(Ⅱ), 2). These compounds were characterized by elemental analyses, IRand UVspectra. Their molecular structures are finally determined by X-ray crystallography. The results reveal that Ls coordinates with metal ions as an anionic tridentate [ONN] ligand forming mononuclear distorted octahedral complexes. The complex 1 is linked by C-H…π interactions to generate a 2Dlayers, whereas 2 is linked by C-H…π interactions and C-H…Oand C-H…N H-bonding to form a 3D framework. |
