Question:

(a) Give an account of the methods of synthesis of Rh(IV) and Ir(IV) halides and halido anions.

(b) Reaction of [IrCl₆]²⁻ with PPh₃ and Na[BH₄] in EtOH gives [IrH₃(PPh₃)₃]. Give the structures of the isomers of this complex and suggest how you would distinguish between them using NMR spectroscopy.
