5-Chloro-2, 4-Dihydroxy Butyrophenone oxime (CDHBO) has been successfully employed as a reagent for spectrophotometric determination for Mn(II) at pH range 7.0 to 11.0 in chloroform medium. The composition of the complex 1:2 (metal:ligand) has been confirm by job's method for continuous variation, Yoe & jones mole ratio method & slope ratio method. The stability constant of the complex is found to be 3.94107. The dark brown coloured complex obeys Beer's law over the concentration rangei to 10 ppm for Mn(II) ion. The complex has molar absorptivity 6.0 103 mol-1 cm -1.While their sensitivity is 0.009 μg Mn/cm2.Limits of interference due to the presence of foreign ions in the spectrophotometric determination has also been determined. The standard free energy of the complex is 10.442 Kcal/mole at 30°C. The complex is stable for one week, CDHBO has also been found to give quite satisfactory results for Mn(II) present in synthetic mixtures. The antimicrobial activity of CDHBO and Mn-CDHBO complex have also been calculated.
