Question 3 Answer all parts. (a) Consider the following complexes and the data pertaining to them: Complex A (cm) 2. (cm) Measured Heff (us) at 298 K 1 (pyH)3[TiClo] 12750 155 1.78 2 2 (Et4N)2[NiCl4] 3500 -315 3.90 3 Ba[MnF] 22000 199 3.80 4 [Fe(OH2).]2(SO4)3 14000 0 5.92 py = pyridine, C3H5N. (i) Using ligand-field splitting diagrams, determine the complex ion ground term for each of compounds 1-4. Ensure you include the spin multiplicity and symmetry label. [8 marks) (ii) For each complex, calculate the effective magnetic moment (Heft) using the appropriate equation. Make sure you show your working. [8 marks) (b) Compare your calculated ueff values for complexes 1-4 with the measured values given in the table. Account for any differences that arise. [4 marks)
