Thermo-Physical Properties of Some Coumarin Complexes
M. G. Abd El Wahed, K. El Manakhly, N. El Khososy, A. El Farargy
A number of complexes of transition metal ions with some coumarin derivatives have been prepared and their structures were elucidated with the help of conductometric, photometric and infrared studies. The stability constants of various complexes were determined, in aqueous medium, at different temperatures potentiometrically. The thermodynamic characteristics, ΔG, ΔH and ΔS, were calculated. The electrical behaviour of prepared compounds was followed.
