ABSTRACT:
Schiff base ligands have structures which enable them to act as chelating agents. The formation of Mn(III) complex with 2z-2-benzylidenehydrazinecarbothioamide has been studied spectrophotometrically at an absorption maximum of 635 nm at different temperatures. The data show that Mn(III) and 2z-2-benzylidenehydrazinecarbothioamide combine in the molar ratio of 1:3. The stability constants of the complex were calculated to be 6.70 x 1014, 5.60 x1014 and 1.16 x 1014, 4.30 x 1014 by continuous variation method and mole ratio method at 25°C and 40°C respectively. The immediately formed complex shows stability with respect to temperature.
