将配体L[2,5-二-(3,5-二甲基吡唑-4-巯基)-1,3,4-噻二唑]与Co(NO3)2 6H2O,Cd(NO3)2 4H2O和MnCl2 4H2O进行配位反应,得到三个配合物[Co(L)2(H2O)4](NO3)2 4(CH3CH2OH)(1),[Cd(L)2(H2O)4](NO3)2 4(CH3CH2OH)(2),[Mn(L)2(Cl)2(CH3OH)2]2(CH3OH)(3),并用元素分析,FT-IR和X射线单晶衍射进行了表征.分析结果表明,配体L呈"U"形,配合物1~3呈"S"形.配合物中Co(II),Cd(II),Mn(II)的配位环境均为扭曲八面体,每个金属离子同时和两个配体进行配位.配体和配合物体外抑菌活性研究结果表明,配体及其配合物都有一定的抑菌活性.
Three complexes [Co(L)2(H2O)4](NO3)2·4(CH3CH2OH)(1), [Cd(L)2(H2O)4](NO3)2·4(CH3CH2- OH) (2) and [Mn(L)2(Cl)2(CH3OH)2]·2(CH3OH) (3) were synthesized from the reaction of 2,5-bis(3,5- dimethylpyrazol-4-thio)-3,4-thiadiazole with Co(NO3)2·6H2O, Cd(NO3)2·4H2O and MnCI2.4H2O, and characterized by elemental analysis, FT-IR and single crystal X-ray diffraction. The results of structural analysis indicate that the ligand (L) was adopted "U" configuration, and each complex shows a "S" conformation. In three complexes, the coordination environment of each metal center show a distorted octahedral geometry, and each metal ion was coordinated with two ligands. The bacteriostatic activity results indicated that both of the ligand and complexes possess some bacteriostatic effect.
