them from chemical syntheses. Cyclic voltammograms for [RhL2Cl4]–(L = PEt3, SMe2, SeMe2, or py) show that oxidation occurs at more positive potentials, but the rhodium(IV) complexes are unstable. Neutral iridium(III) complexes [IrL3X3] are not oxidised by X2 or HNO3, and possible reasons for this and the crucial role of the [IrL2X4]– intermediates in the preparation of [IrL2X4] are discussed.

trimethylarsine. Trifluoroiodomethane also reacts with the compounds (CH3)2AsX (X = C6H5, Cl, I) and CH3AsI2 to give CH3As(CF3)2; and in most of these reactions the compound CH3As(CF3)I is also formed, which is converted to the compound CH3As(CF3)Cl by reaction with silver chloride.

The known nickel(III) complexes [Ni(PR3)2X3]) (X = Cl, Br) with monodentate phosphines (PMe3, PEt3, PnBu3, PMe2Ph X = Br only) have been reexamined, some being obtaines in a pure state for the first time. New complexes with PMe2Ph, PEt2Ph and PMePh2 are described. Detailed spectroscopic data (IR, UV/Visible and EPR) are reported and assigned for all complexes, leading to the proposal of trans-trigonal

[Mn2(CO)8L2][L = PPh(OMe)2 and P(OMe)3]. Thermal reactions of [Mn2(CO)10] with an excess of L [L = PMePh2,PEtPh2,PMe2Ph, PPh(OMe)2, and P(OMe)3] in high boiling solvents give the hydrido-complexes mer-trans-[Mn(CO)3HL2] which are more conveniently prepared using Na[BH4] in refluxing ethanol. Treatment of the hydrides with HPF6 in acetonitrile gives the salts [Mn(CO)3(NCMe)L2][PF6]. Other cationic complexes of

Reactions of Y[Os(N)X4] and Y[Ru(N)Cl4](Y = Ph4As or Bun4N; X = Cl or Br) with arsines, stibines, and 2,2′-bipyridyl (bipy) give the nitrido-complexes [Os(N)X3L2] and [Ru(N)Cl3(QPh3)2](L = QPh3, AsEt3, or ½bipy; Q = As or Sb), but tertiary phosphines give reduced species. Reaction of tertiary phosphines with [M(N)Cl3(AsPh3)2](M = Os or Ru) give the phosphine imidato-complexes [M(NPR3)Cl3(PR3)2](PR3=
