Purple (py=pyridine) is conveniently obtained by reaction of trans- with HCl gas and NEt4Cl in CH2Cl2 solution.Reduction of this anion with ascorbic acid, followed by successive treatment with L (L=SMe2, SeMe2, PPh3, AsPh3, or SbPh3), Cl2, and HCl, afford , which have been characterised by analysis, i.r. and u.v.-visible spectroscopy, and conductance measurements.The potentials for the reductions were measured, and the formal potential for the IrIII-IrIV couples are compared with those of trans-0/- and cis-0/- (L-L = bidentate ligand analogue of L).
