Synthesis of hydridotriosmium complexes containing isomeric μ-carboxamido, {μ(O, C)-OC(NHR)}, μ-formamido, {μ(O, N)-OC(H)N(R)}, and μ-iminyl, {μ(C, N)-C(OR′)=NR}, groups. Crystal and molecular structure of Os3{μ-H,μ-C(OR′)=NCH3}(CO)10, R′ = C (=O)NHCH3

the range −10 to 25 ° C. One mole of CO is evolved and a μ(O,C)-carboxamido complex (1) is isolated in high yield: Os3μ-H,μ-OCNR′R}(CO)10 (1a, R = Me, R′= H; 1b, R = R′ = Me; 1c, R = n-Pr, R′ = H, 1d, R = n-Bu, R′ = H; 1e, R = Et, R′ = H). The 1H NMR spectrum of 1e indicates the existence of two isomers due to the restricted rotation around the CN bond of the μ-carboxamido group.
