The Complexation reaction between Sodium (2S,5R,6R)-6-{[(2R)-2-amino-2-phenylacetyl]amino}-3,3-dimethyl-7-oxo-4-thia-1-azabicyclo[3.2.0]heptane-2-carboxylate (Ampicillin sodium salt) ligand with Ca+2 and Ba+2 ions were studied condctometrically in methanol at four different temperatures (293.15K, 298.15K, 303.15K, 308.15K) On drawing the relation between molar conductance and the ratio of metal to ligand concentrations, different lines are obtained indicating the formation of (1:1 and 2:1 (M:L) stoichiometric complexes. The formation constants, thermodynamic parameters Gibbs free energies and Gibbs free energies of formation of different complexes in methanol were determined.
