Question 3 Answer all parts. (a) Consider the following complexes and the data pertaining to them: Complex A (cm-1) a (cm-1) Measured Ueff (UB) at 298 K 1 (pyH)3[TiC16] 12750 155 1.78 2 (Et4N)2[NiCl4] 3500 -315 3.90 3 Ba[MnF6] 22000 199 3.80 4 [Fe(OH2)6]2(SO4)3 14000 0 5.92 py=pyridine, C5H5N. — (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 (left) using the appropriate equation. Make sure you show your working. [8 marks] (b) Compare your calculated Meff values for complexes 1-4 with the measured values given in the table. Account for any differences that arise. [4 marks]
