Decacarbonyl(μ-ethylidenimino-1κN:2κC)-μ-hydrido-triangulo-triosmium(3 Os–Os)

Abstract

The title complex, [Os3(C2H4N)H(CO)10] or [Os3(CO)10(μ-H)(μ-HN=C—CH3-1κN:2κC)], was synthesized in 41.6% yield by reactions between Os3(CO)11(CH3CN) and 2,4,6-trimethylhexahydro-1,3,5-triazine. The central osmium triangle has two OsI atoms bridged by a hydride ligand and a μ-HN= C—CH3-1κN:2κC triazine fragment. Three CO ligands complete the coordination sphere around each OsI atom, while the remaining Os0 atom has four CO ligands. Each Os atom exhibits a pseudo-octahedral coordination environment, discounting the bridging Os—Os bond.
