Abstract
The kinetics and mechanism of substitution of some ironII–triazine complexes namely textFetextPDT 32 + textFetextPDTS 34 textFetextPPDT 32 + and textFetextPPDTS 37 PDT = 32phenyl56diphenyl124triazine PDTS = 32pyridyl56bis4phenylsulfonicacid124triazine disodium salt PPDT = 34phenyl2pyridyl56diphenyl124triazine and PPDTS = 344phenylsulfonicacid2pyridyl56bis4phenylsulfonicacid124triazine trisodium salt by 110phenanthroline phen have been studied by conventional spectrophotometry in acetate buffers over the pH range 36–56 by following the absorbance of the triazine tz complexes at their respective absorption maxima The reactions were carried out under pseudofirstorder conditions that is phen ≫ FeII–triazine The reactions were found to be first order in both FeIItriazine complex and phen The rates increase with increasing pH Plots of k obs versus phen are linear with positive intercepts and also plots of k obs against 1/H+ are linear with positive intercepts on the rate axes indicating that the reactions proceed by both phen– and hydrogen ion–dependent and independent paths From the kinetic data obtained at 25–55 °C the specific rate constants and thermodynamic parameters have been computed
