STRUCTURE OF Cu(Ⅱ)-(B15, C-5) COMPLEX

【摘要】 <正> There have been many works on alkali and earth alkali-metal crown complexes. Due to the large solvation energy of metal ions, coupled with the inherent poor basic character of oxygen in —CH₂—O—CH₂— unit, only very little is known about transition metal complexes of crown ether. From the viewpoint of the model system for Cu（Ⅱ） site in metalloproteins, the study of copper crown complexes has drawn much interest. The conclusion that there was no reaction between the Cu（Ⅱ） and （B15-C-5） in methanol-H₂O solvent was drawn from the study of thermo-effeet. By using UB-Vis更多还原
