Question

The oxalate dianion or 'ox' (C2042) can act as a bidentate ligand. a) Explain what is meant by the term 'bidentate". B3. (1 mark) b) Reaction of FeClh.6H20 (1 mmol) with 'ox (3 mmol) in aqueous solution forms several octahedral complexes. Draw all possible isomers for the product of this reaction, indicating the charge on the complex ions (3 marks) c) Give the name for the type of stereoisomerism observed and hence assign and label each of the stereoisomers from b) with an appropriate description d) The magnetic moment for one of the products from question B3 b) yields a value of 5.92 B.M. Using this information, sketch a fully labelled ligand field splitting diagram for this complex, clearly showing the 3d orbital occupancy
