Abstract

The new pentanuclear complex Ru5(CO)114-O)(µ 3-H)(p-MeC6H4C(O)C(H)=CPh)3 was synthesized by the reaction of Ru3(CO)12 with 3-phenyl-1-p-tolylprop-2-en-1-one. The complex was characterized by elemental analysis and NMR and IR spectroscopy. The crystal structure of the complex was established by X-ray diffraction. Three of five ruthenium atoms form five-membered oxaruthenacycles with the organic ligands. The complex with an unusual structure has 84 valence electrons and is stabilized by one bridging µ4-O ligand in a square-planar environment, one bridging µ3-H ligand located in the plane passing through three ruthenium atoms, and a semibridging interaction with one of the carbonyl groups.
