摘要

A new chelate ligand, 5-methyl-lH-pyrazole-3-carboxylic acid (mpca), has been synthesized. This ligand reacts with cupric sulfate to give two supramolecular compounds [Cu(mpca)_2(H_2O)] centre dot 3H_2O (1) and [Cu_2(mpca)_2(pyr)_4] (Pyr = pyridine) (2), which were characterized by elemental analysis and X-ray crystal diffraction. Helical water chain and strong pi-pi interaction are important for the stability of the 3-D structure of these supramolecules.
