Linear Free Energy Relationships of Complexes(XIX)
Abstract:
The stability constants of 5-substituted phenanthroline-12-(2'-hydroxy 1-5substituted benzy1)-1,4,7,10-tetraazacyclotr and copper(Ⅱ) ternary mixed ligand complex compounds were determined by pH method at 25.0±0.1 ℃ in the presence of 0.1 mol•dm-3KNO3. The form of coordination macrocyclopolyamine ligandcopper(Ⅱ)-5-substituted phenanthroline in aqueous solution were studied. The formation of d-π back bonding between copper(Ⅱ ) and nitrogen heteronuclear aromatic base has been proved. The tendency of stability of the ternary complexes have been explained by electron effects and d-π back bonding.
