摘要

Three novel complexes [Cu（L1）2（H2O）2] （1）, [Ni（L1）2（H2O）2]·（H2O）4（2,HL1=5-methyl-1-（4-methylphenyl）-1,2,3-triazole-4-carboxylic acid） and [Ni2 （HL2）2（CH3OH）6]·（CH3OH）2（3,H3L2=1,2,3-triazole-4,5-dicarboxylic acid） were synthesized and characterized by elemental analysis, IR and X-ray diffraction. Complexes 1 and 2 are mononuclear structures, and are assembled into a two-dimensional sheet by C（7） H（7）···O（3） weak interactions or hydrogen-bonding interaction. Complex 3 is a centrosymmetric dinuclear structure, and is assembled into a three-dimensional supramolecular structure by hydrogen-bonding interaction.
