摘要：

Iodoruthenium(II) complexes trans-[Ru(L-L)(2)I-2] (L-L=Ph(2)PCH(2)CH(2)PPh(2), cis-Ph(2)PCHCHPPh(2), Ph(2)AsCH(2)CH(2)AsPh(2), o-C6H4(AsMe(2))(2)), trans-[Ru(SbPh(3))(4)I-2] and [Ru(PPh(3))(3)I-2] have been made by reaction of [Ru(H2O)(6)][BF4](2) with the ligand and NaI in aqueous ethanol. Oxidation with cone. HNO3-HBF4 yielded trans-[Ru(L-L)(2)I-2]BF4. The complexes were characterised by spectroscopy (IR, UV-Vis, P-31 NMR) and cyclic voltammetry, and their properties compared with chloro- and bromo- analogues. Unsuccessful attempts to prepare palladium(IV) iodo complexes [Pd(L-L)(2)I-2][BF4](2) are described. The crystal structures of [Ru(Ph(2)AsCH(2)CH(2)AsPh(2))(2)I-2]BF4 and [Pd{o-C6H4(PMe(2))(2)}Cl-2(2)][BF4](2) are reported.
