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 1.1010g (~2 mmol) (NH4)2CeNO3 in 20 mL of DI water.
  • Dissolved 1.5993g (~0.5 mmol) 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 1M NaOH under stirring.
  • Refluxed solution for 2 hours at 80°C.
  • The resulting solution was filtered using a scintered glass funnel and vacuum filter.

Results

The solution that was produced was milky yellow and moved extremely slowly through the filter. As a result, it did not completely filter today. Filtration will be resumed on Monday.
