Question: Tetrahedral complexes of Co2 are quite common Use a d orbital
Tetrahedral complexes of Co2+ are quite common. Use a d-orbital splitting diagram to rationalize the stability of Co2+ tetrahedral complex ions.
Answer to relevant QuestionsWhy do tetrahedral complex ions have a different crystal field diagram than octahedral complex ions? Why are vir-tually all tetrahedral complex ions “high spin”? Acetylacetone, abbreviated acacH, is a bidentate ligand. It loses a proton and coordinates as acac-, as shown below: The equilibrium constant Ka for the reaction is 6.0 X 10-3. Consider the following data: where en = ethylenediamine. b. Based on your answer to part a, which is the stronger oxidizing agent, Co3+ or Co(en)33+? c. Use the crystal field model to rationalize the result in part b. In each of the following radioactive decay processes, supply the missing particle. a. 73Ga →73Ge + ? b. 192Pt → 188Os + ? c. 205Bi → 205Pb + ? d. 241Cm +? → 241Am e. 60Co → 60Ni + ? f. 97Tc + ? → 97Mo g. 99Tc → ...
