Abstract  

The isotopic exchange rate of thiourea in hexa(thiourea) plumbous nitrate was determined at two different concentrations. The results showed that the complex is unstable in the kinetic sense. The rate of exchange increases with increase of concentration of the free ligand and also of the complex. Furthermore, the results indicated that an increase in temperature by 15°C does not influence the rate to any significant degree.
