The heat effects of formation of silver(1) mono- and bicomplexes with pyridine in a methanol-dimethylformamide binary solvent with different compositions at 298.15 K were determined by calorimetry. The changes in the entropy and Gibbs energy of these reactions were calculated, and the effect of the solvent composition on the shift of equilibrium of the complex formation reactions were considered. The contributions of the enthalpy of solvation of the reactants and the change in the heat effects of the reactions were analyzed.
