摘要：

The different complexation thermodynamic parameters for example, formation constants (K-f), free energies of formation (Delta G(f)) enthalpies of formation (Delta H-f) and entropies of formation (Delta S-f) for nano copper nitrate hemi pentahydrate (Cu(NO3)(2).2.5H(2)O) with 4,6-diacetylresorcinol as a ligand in pure DMF and in mixed solvents of DMF and water are calculated at different temperatures, 293.15, 303.15, 313.15 and 323.15 K by using conductance measurements. By drawing the relation between molar conductance and ratio of metal to ligand, the figures indicate the formation of two types of complexes with M:L ratios 1:2 and 1:1 stoichiometric complexes.
