摘要：

The syntheses of the cis octahedral complexes [Rh(tetas)X(2)]BF4 (tetas=As(o-C(6)H(4)AsMe(2))(3); X=Cl, Br or I) and [Ir(tetas)X(2)]X are described. Fac-[Rh{MeC(CH(2)AsMe(2))3}X(3)] and [Ir{MeC(CH(2)AsMe(2))(3)}Cl-3] were also obtained. The complexes were characterised by analysis, UV-Vis and multinuclear NMR (H-1 and Rh-103) spectroscopies. Cyclic voltammetry revealed irreversible reductions to Rh(I) or Ir(I). The reaction of trans-[Ir(CO)(PPh(3))(2)Cl] with tetas, followed by chlorine oxidation gave the Ir(III) carbonyl [Ir(tetas)(CO)Cl][BF4](2) which was characterised by a single crystal X-ray study (Ir-As=2.392( 1)-2.464(1), Ir-Cl=2.425(2), Ir-C(O)=1.934(8) Angstrom).
