(μ-H)2Os3(CO)10 was found to react with C6H5(H)C=NCH3 in refluxing hexanes solution to produce the compounds (μ-H)2(μ-N(CH3)CH2C6H 4)Os3(CO)9, A, and (μ-H)(μ-η2-C6H5C=NCH 3)Os3(CO)10, B. A has been studied by IR, 1H NMR, and X-ray crystallographic analyses. Crystal data: space group Pbca (D2h15, No. 61; a = 13.198 (4), b = 21.254 (6), c = 15.129 (5) Å, V= 4244 (4) Å3, mol wt 943.88; Z = 8; ρcalcd = 2.95 g cm-3. For 2228 reflections (F2 ≥ 3.0σ(F2)), collected by counter techniques, R1 = 0.052 and R2 = 0.057. A contains a triangular cluster of osmium atoms, nine terminal carbonyl ligands, two bridging hydride ligands, and a μ-N(CH3)CH2C6H4 ligand which bridges an edge of the cluster through the nitrogen atom and contains an ortho-metalated phenyl ring. The complex was evidently formed by the addition of one molecule of imine to the cluster, transfer of one hydrogen atom from the cluster to the iminyl group, loss of a carbonyl ligand, and ortho metalation of the phenyl ring. B was apparently formed by addition of the imine to the cluster, abstraction of a hydrogen atom from the iminyl carbon, and loss of H2 from the cluster.
