| 摘要: 在溶剂热条件下合成了2种含HL（HL=（N-（3-甲基亚水杨基）吲哚乙胺）配体的金属配合物Ni（L）2（1）和Cu（L）2（2），并通过热重分析、红外光谱、元素分析和单晶X射线衍射表征其结构。配合物1和2均属于单斜晶系，空间群为P21/n。配合物1的晶胞参数为a=1.481 6（7）nm，b=1.310 0（6）nm，c=1.668 7（7）nm，β=111.346（7）°，配合物2的晶胞参数为a=1.479 7（2）nm，b=1.299 41（19）nm，c=1.667 6（2）nm，β=111.537（3）°。配合物1和2具有类似的单核结构，通过分子内C-H…O氢键和分子间D-H…π氢键作用分别将其进一步延伸为三维超分子结构。而且，通过琼脂扩散法对配合物和配体的抗菌活性进行了细致的筛选，实验结果表明配合物1和2比配体具有更优异的抑菌效应。 |

| Abstract: The title complexes, Ni(L)2 (1) and Cu(L)2 (2) based on HL (HL=N-(3-methylsalicylidene)tryptamine) have been synthesized under solvothermal conditions and characterized structurally by TGA, infrared spectra, elemental analysis and single-crystal X-ray diffraction. Complexes 1 and 2 both crystallize in monoclinic system, and the space groups are P21/n with the unit cell parameters for complex 1:a=1.481 6(7) nm, b=1.310 0(6) nm, c=1.668 7(7) nm, β=111.346(7)°, and for complex 2:a=1.479 7(2) nm, b=1.299 41(19) nm, c=1.667 6(2) nm, β=111.537(3)°. Complexes 1 and 2 possess the similar mononuclear structures, which are further extended into infinite 3D supramolecular frameworks by intramolecular C-H…O hydrogen bonds and intermolecular D-H…π hydrogen bonds, respectively. Furthermore, the complexes and the ligand have been investigated for their preliminary antibacterial activities in detail by agar diffusion method, and the results demonstrate that complexes 1 and 2 display more excellent inhibiting effects than the ligand. |
