RESUMO

The thermodynamic properties [pK, and delta G, delta H and delta [delta S] for the ionization of p-nitrabenzeneazaresarcinol were evaluated. The interaction between such ligand and Co, Ni and Cu was discussed. The data were found to follow the William-Irving order

RESUMO

The formation constants of mixed ligand complexes of copper [II]-4-Nitrobenzeneazoresorcinol complex with unidentate ligands were determined by spectrophometric method at 25°C. The data of the inner sphere complex are related with both the electron donor and basicity constants of the unidentate ligands

RESUMO

The dielectric constants of DMF, DMA and THF-H[2]O systems at different temperatures were used to apply Akerlof linear relationship, the values of a and b coefficients were recorded. The dielectric relaxation was calculated for the three systems at 25?C and the results were discussed in light of viscosity permitivity epsilon" and excess dielectric constant delta epsilon
