| Abstract: Five complexes[Co(HL)2(H2O)2](NO3)2(1),[Cu2(L)2(NO3)2(H2O)4] (2),[Cu2(L)2(AcO)2(H2O)2]·6H2O (3),[Cu2(L)2(HL)2(ClO4)2]·2CH3CN (4) and[Cd2(L)2(HL)2(NO3)2]·2H2O (5) utilizing 3-(2-pyridyl)-1,2,4-triazole ligand(HL) as well as different metal salts have been synthesized and structurally characterized by single crystal X-ray diffraction, infrared spectroscopy (IR), elemental analysis, powder X-ray diffraction (PXRD) and thermogravimetric analysis (TGA). The structural analyses reveal that complex 1 has a mononuclear structure and forms a 2D supramolecular structure via hydrogen bonding interactions. Complexes 2~5 have dinuclear structures. Complexes 2 and 5 are arranged into 2D supramolecular structurs by the corresponding hydrogen bonding interactions, and complex 3 is also arranged into a 3D supramolecular structure through hydrogen bonding interactions. The coordination modes of HL ligand in the complexes were studied. Moreover, the fluorescent properties and fluorescence lifetimes of ligand HL, complexes 1 and 5 were investigated in the solid at room temperature. |
