  Abstract The reaction of [HOs(CO) 4 ]PPN with [Re(CO) 5 - Br] gives the new heterobimetallic complex anion [HOsRe(CO) 8 Br]PPN in high yield and the neutral complex [HOsRe(CO) 9 ] as a minor product (PPN is the bis(triphenylphosphine)iminium cation). The molecular structure of [HOsRe(CO) 8 Br]PPN has been determined by X-ray crystallography. The crystals are triclinic, space group P 1 with a = 11.762(2)

  complex (H/sub 2/Os(CO)/sub 4/) is deprotonated upon adsorption on the basic surface of magnesia. The resulting (HOs(CO)/sub 4/)/sup -/ is held strongly to the surface by a localized carbonyl-Mg/sup 2 +/ interaction analogous to the contact anion ion pairing observed for (Na)(HOs(CO)/sub 4/) in THF. The surface-bound complex is the precursor of surface species that are catalytically active for CO hydrogenation

  The compound (PPN)[HOs(CO)4] reacts readily with [IrCl(eta-2-dppm)2] (PPN+ = (Ph3P)2N+, dppm = Ph2PCH2PPh2) at ambient temperature, yielding the heterobinuclear complex [IrOs(H)2(CO)3(mu-2-eta-3-(o-C6H4)PhPCH2PPh2)(dppm)] (1), in which one phenyl group is ortho-metalated at the Ir center. Treatment of 1 with the electrophile sources HBF4.Et2O or [AuPPh3]BF4 reverses the ortho metalation to give the hydrido-bridged species, [IrOs(CO)3(mu-H)(mu-X)(dppm)2][BF4] (X = H (2), AuPPh3 (3)). Deprotonation of 2 with use of NaH regenerates compound 1. The AuPPh3 group in 3 is readily replaced by an iodo group in the reaction with I2 to give [IrOs(CO)3(mu-H)(mu-I)(dppm)][TBF4] (4). Under a CO atmosphere, compound 2 yields [IrOs(CO)5(dppm)2][BF4] (5), and reaction of 5 with Me3NO.2H2O results in loss of one carbonyl group from the Ir center to yield [IrOs(CO)4(dppm)2][BF4] (6). The structure of 5 has been determined by X-ray techniques. This compound crystallizes, together with 1.5 equiv of CH2Cl2, in monoclinic space group P2(1)/c, with cell parameters a = 12.063 (2) angstrom, b = 22.725 (3) angstrom, c = 22.050 (3) angstrom, beta = 101.66 (1)-degrees, V = 5920 angstrom-3, and Z = 4. The structure has refined to R = 0.043 and R(w) = 0.043 and R(w) = 0.063 on the basis 5515 unique observations with 444 parameters varied. Compound 5 has a trans-bridging arrangement of diphosphine ligands and has two carbonyls bound to Ir and three on Os. The carbonyl and phosphine arrangement on Os suggests a trigonal bipyramidal (TBP) arrangement characteristic of Os(0), which then forms a dative Os --> Ir bond to the Ir(+I) center, giving it a TBP geometry also. The Os-Ir separation of 2.9652 (4) angstrom is at the long end of the range expected for a normal single bond.
