The reactions of ozone with Ru2+ and Ru3+ complexes of the oxidatively robust ligand TPA (TPA = tris(2-pyridylmethyl)amine) are studied. In THF solution at –78 °C the complexes [Ru(TPA)(DMSO)Cl]Cl and [RuCl(TPA)]2(PF6)2 do not undergo any significant reaction with O3, in contrast to the previously reported reactions of RuCl3•3H2O with O3 in aqueous solution. In addition, the reactions of Cr3+ ethylenediamine (en) complexes are also studied. The complex [cis-Cr(en)2Cl2]Cl does not react with O3 in THF at –78 °C, but the corresponding triflate (CF3SO3-) does.
