Complex A has the formula Co(MIMT)4(NO3)2, while Complex B has the formula Co(MIMT)2(NO3)2. Will the magnetic moments of complexes A and B be affected by whether they are thione or thiol complexes? If we had experimentally measured the magnetic moments of A and B, could that data have been used to determine their coordination geometries? Explain your answer.
Complex A has the formula Co(MIMT)4(NO3)2, while Complex B has the formula Co(MIMT)2(NO3)2. Will the choice of coordinating ligands, with nitrogen or sulfur donors, affect the magnetic moments of tetrahedral Co2+ and Co3+ complexes? Will the choice of ligands affect the magnetic moments of octahedral Co2+ and Co3+ complexes? Draw crystal field diagrams to justify your answers.
