摘要

Six new macrocyclic complexes were synthesized by a template reaction of 1,4-bis(2-formylphenoxy)butane with diamines and Cu(NO3)2·3H2O and their structures were proposed on the basis of elemental analysis, FT-IR,UV-Vis, magnetic susceptibility measurements, molar conductivity measurements and mass spectra. The metal to ligand molar ratios of the Cu(Ⅱ) complexes were found to be 1∶1. The Cu(Ⅱ) complexes are 1∶2 electrolytes as shown by their molar conductivities (Λm) in DMF at 10-3 mol·L-1. Due to the existence of free ions the Cu(Ⅱ)complexes are electrically conductive. Their configurations were proposed to be probably distorted octahedral.
