Abstract

Abstract: Equilibrium constants for mono-and bisligation of imidazole (ImH) with (meso- tetrakis (2, 6-dimethylphenyl)-porphinato) manganese (III) chloride ((Me8TPP) Mn"'C1) have been determined so that the concentrations (dry CH2C12) of the three species (Me8TPP) Mn"'C1,[(Me8TPP) Mn"'(ImH)] cl, and [(Me8TPP) Mn11'(ImH) 2] Cl may be calculated at different ImH concentrations. The equilibrium constants for ligation of the one and two ...
