Thermodynamic parameters and biological effects of nano-CuCO3 with dibenzo 18-C-6 in mixed solvents

[Display omitted] •Formation thermodynamic parameters were calculated using conductance measurements.•Provement the most stable complex using thermodynamic parameters.•The new prepared complex has a dual effect as an antitumor and antioxidants.•Comparison between thermodynamic parameters for two complexes is occurs. Formation thermodynamic parameters of nano copper carbonate with dibenzo 18-crown-6 (18-C-6) as a ligand was studied. The calculations are obtained using conductance measurements. The complex was formed in ethanol – water mixed solvents and the study was occurred at different temperatures. Also, the biological effect of complex was studied. The new prepared complex has dual effect as an antitumor and antioxidants compound.
