3. The 0 parameter for [Co(acac)2(H2O)2] and [CoIII(acac)3] can also be determined from UV-vis data. The values are 9,000 and 22,806cm1, respectively. Compare the magnitude of the 0 parameters for the two cobalt complexes and suggest a possible reason for such a difference [assume the ligand field interaction is the same for both complexes]. [2]
