Unusual High Stability of Dinuclear Copper(Ⅱ) Complexes with a Dinuleating-24-Macrocyclic Ligand
【Abstract】 The macrocyclic dinuclear copper(Ⅱ) complex Cu\-2LCl\-2·2H\-2O was prepared in anhydrous ethanol, and characterized by means of element analysis, IR.The stepwise stability constants of the 1∶1 and 2∶1 ([Cu]/[L]) complexes were determined by potentiometric titration in KCl supporting electrolyte (0 100 mol/L) at 25 ℃.The results indicate that L shows unusual high stability to dinuclear copper(Ⅱ) ions.
