| 摘要: 本文以水杨醛和N，N′-(2-胺基苯基)-2，6-二甲酰亚胺吡啶进行缩合得到席夫碱化合物L，然后与CuCl2·2H2O分别在甲醇、乙醇溶液中进行配位反应；在进行配位反应中，化合物L的一端酰胺键发生醇解，分别被甲醇，乙醇取代，从而，得到了吡啶酰胺一端被甲醇，乙醇取代的席夫碱铜(Ⅱ)单核配合物1和2。用元素分析，FTIR和X-射线单晶衍射进行了表征。结果表明，化合物L属于三斜晶系，空间群P1，配合物1和2都属于单斜晶系，空间群都为 P21/c，配合物1和2均为单核配合物。配合物2通过弱相互作用形成二聚体。 |

| Abstract: The Schiff base compound L was synthesized from condensation reaction of salicylaldehyde with N,N′-(2-amidogen benzyl)-2,6-two formyl imines pyridine. CuCl2·2H2O react with L in methanol or ethanol solution. During the coordination reaction of the compound L of one end of the amide alcoholysis occurred, were methanol, ethanol replaced, thus, be obtained at one end of picolinamide methanol, ethanol substituted schiff base copper(Ⅱ) mononuclear complexes 1 and 2, and characterized by elemental analysis, FTIR and single crystal X-ray diffraction. The results of structural analysis indicate that the compound crystallizes in the triclinic crystallize and space group P1, two complexes in the monoclinic crystallize, space group P21/c. Complexes 1 and 2 belong to mononuclear complexes. The two complex 2 were linked with weak intermolecular forming the dimer. CCDC: 843076, L; 843077, 1; 843078, 2. |
