Iodoruthenium (II) complexes trans-[Ru(L-L)2I2] (L-L=Ph2PCH2CH2PPh2, cis-Ph2PCHCHPPh2, Ph2AsCH2CH2AsPh2, o-C6H4-(AsMe2)2), trans-[Ru(SbPh3)4I2] and [Ru(PPh3)3I2] have been made by reaction of [Ru(H2O)6] [BF4]2 with the ligand and NaI in aqueous ethanol. Oxidation with conc. HNO3-HBF4 yielded trans-[Ru(L-L)2I2]BF4. The complexes were characterised by spectroscopy (IR, UV-Vis, 31P NMR) and cyclic voltammetry
