Abstract– With good entropy change values, the complexes of Monothio-β-diketone have good therapeutic importance. These complexes play vital role in biological system in both human beings and plants. Overall Stability constants of bivalent complexes of Manganese, Nickel, Palladium and Platinum with para-chlorobenzoylthioacetophenone an organic ligand have been determined potentiometrically at three different temperatures viz. 10°C, 20°C and 30°C. From a knowledge of Stability Constant data, Standard Changes in Free energy, Enthalpy and Entropy were determined with the help of appropriate methods. The Standard change in entropy of the above complexes together with their medicinal significance have been discussed.

Key words: Overall Stability constant, Potentiometric technique, Standard change in Entropy, Medicinal significance, Therapeutic importance
