Hydrolysis of pyrophosphate to orthophosphate promoted by cobalt(III). Evidence for the role of polynuclear species

Complex formation between N4CoIII(aq) and pyrophosphate and its influence on the hydrolysis of pyrophosphate to orthophosphate have been studied by means of 31P NMR over the pH range 0-12. Most experiments were undertaken with N4 = (tn)2; for comparison (en)2 and tren were also examined. There is evidence that the reactive species in regard to hydrolysis is a 3:1 N4CoIII-pyrophosphate complex. At 25°C and pH 7,t1/2 is 1 h, compared with 10 years for corresponding solutions in the absence of cobalt complexes; the enhancement in rate is thus ～105.
