Objective

Adopting the protocol for the synthesis of [CeK(H2O)12][Ce(H2O)6]2[(H2O)4CeBW11O39H]2·20H2O, a synthesis was performed using (NH4)2CeNO3 rather than Ce(NO3)3.

Protocol

  • Dissolved 0.110g (NH4)2CeNO3 in 20 mL of DI water.
  • Dissolved 1.602g K8[BW11O39H]·13H2O in 40 mL of DI water.
  • Added the second solution to the first solution and adjusted the pH to 3.5 using 6 M HCl under stirring.
  • Refluxed solution for 2 hours at 80°C.

Results

It was discovered after performing the above protocol that the amount of (NH4)2CeNO3 used was 1/10 what should have been used. As a result, the solution produced was discarded and the synthesis was performed again with the proper quantities the following day.
