Abstract:

Thermal effects of coordination reaction of Cu(Ⅱ )-α,α'-bipyridyl-macrocyclic dioxotetraaming ternary complex compounds have been determined in aqueous solution at 25.0±0.1℃ and I=0.1 mol•dm-3 KNO3 by means of model RD-1 automatic conduction calorimeter. Linear thermodynamic function relationships have been found to exist in this ternary system. Thermodynamic properties of Cu(Ⅱ)-bipy/phen-HRTADO ternary systems have been compared and discussed. The effects of substituents and stacking of aromatic ring to the thermodynamic properties Cu(Ⅱ)-bipy/phen-HRTADO ternary systems also have been discussed.

Key words: Copper(II), α,α-Bipyridyl, Macrocyclic dioxotetrammine, Thermochemical property, Linear enthalpy-entropy relationships
