The thermal reaction of Ru3(CO)12 with oximes leads with fragmentation of the trinuclear metal framework to bisoximato-bridged dinuclear complexes of the type Ru2(CO)4(μ2-η2-ONCR1R2)2L2, with L representing intact oxime ligands which, in the case of less bulky substituents R1 and R2, remain bonded as such; with sterically more demanding substituents only complexes can be isolated in which the axial oxime ligands are replaced by tripenyl phosphine.The single-crystal X-ray structure analysis of Ru2(CO)4(μ2-η2-ONCMe2)2(HONCMe2)2 (1) and of Ru2-(CO)4(μ2-η2-ONCMe2)22 (12) show a sawhorse-like arrangement of the Ru2(CO)4 backbone with C2-symmetry.In 1 intramolecular hydrogen bonds were observed between the bridging oximato and the terminal oxime ligands.
