Abstract
The kinetics of the bromide interchange and base hydrolysis of trans-(Rh(tn)2Cl2)+, (tn=propane-1,3-diamine) have been studied. For the bromide interchange the observed pseudo first order rate constant is independent of bromide ion concentration up to 0.2 mol dm−3, whereas for the base hydrolysis the observed pseudo first order rate constant is given by kobs = k1 + k2(OH−) for hydroxide ion concentrations up to 1.0 mol dm−3.
The activation parameters for these two reactions have been determined and are compared with those for similar reactions of other analogous complexes.
