Formation thermodynamic parameters of nano copper (II) acetate monohydrate with 4,6-diacetylresorcinol in mixed solvents

The formation thermodynamic parameters, formation constants (Kf), Gibbs free energies of formation (ΔGf), enthalpies of formation (ΔHf) and entropies of formation (ΔSf) of nano copper (II) acetate monohydrate with 4,6-diacetylresorcinol as a ligand in pure DMF and in mixed DMF - water solvents are measured in different concentrations of dimethylformamide - water mixed solvents (70% DMF, 80% DMF, 90% DMF and 100% DMF) at different temperatures, 293.15, 303.15, 313.15 and 323.15K. The data indicate that three types of complexes with metal to ligand ratios 1:2, 1:1 and 2:1 stoichiometric complexes are formed. A comparison between the thermodynamic parameters of formation for the three complexes is studied. [Display omitted] •Formation thermodynamic parameters were calculated at different temperatures.•Three types of complexes were formed with metal to ligand ratio 1:2, 1:1 and 2:1.•The M:L equal 2:1 complex is the most stable complex.•Complexation of nano copper acetate with 4,6- diacetylresorcenol was studied using conductometric method.
