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 MnCl2·4H2O, 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.
