| 摘要: 由三唑农药烯效唑和多效唑合成了2个铜配合物[CuL41Cl2] (1)和[CuL42Cl2·4H2O] (2)(L1=uniconazole，L2=paclobutrazol)。通过元素分析、红外光谱和X-ray单晶衍射对其结构进行了表征。结构分析表明，1属三斜晶系，P1 空间群，晶胞参数为a=0.895 6(3)nm，b=1.326 7(4) nm，c=1.491 8(4) nm，α=94.828(3)°，β=97.774(3)°，γ=105.280(3)°，V=1.680 8(9) nm3。2属三斜晶系，P1 空间群，晶胞参数为a=1.021 89(19) nm，b=1.329(3) nm，c=1.366 4(3) nm，α=81.564(2)°，β=79.508(2)°，γ=79.185(2)°，V=1.785 3(7) nm3。在2个配合物中，六配位的铜离子都采取扭曲的八面体配位构型，分别来自三唑配体的4个氮原子和2个氯原子配位。1和2都由分子间氢键连接成一维链结构。与相应的配体相比，1和2的抑菌活性明显增强。 |

| Abstract: Two copper complexes [CuL41Cl2] (1) and [CuL42Cl2·4H2O] (2) (L1=Uniconazole,L2=Paclobutrazol) were synthesized with triazole pesticides ligands uniconazole and paclobutrazol by solvothermal condition and structurally characterized by element analysis, IR and single crystal X-ray diffraction. Complex 1 is the Triclinic system, space group P1 with a=0.895 6(3) nm, b=1.326 7(4) nm, c=1.491 8(4) nm, α=94.828(3)°, β=97.774(3)°, γ=105.280(3)°, V=1.680 8(9) nm3. Complex 2 is the Triclinic system, space group P1 with a=1.021 89(19) nm, b=1.329(3) nm, c=1.366 4(3) nm, α=81.564(2)°, β=79.508(2)°, γ=79.185(2)°, V=1.785 3(7) nm3. In two complexes, Each six-coordinated Cu(Ⅱ) adopts a distorted octahedral geometry with four nitrogen atoms from triazole ligands and two Cl ions. 1 and 2 was linked into a one dimensional chain by intermolecular hydrogen bonds. Antibacterial activities of complex 1 and 2 increased significantly than corresponding ligands. CCDC: 931901, 1; 932228, 2. |
