✦ Synopsis

Two 1~3-oxo carboxylate-bridged heterotrinuclear (ruthenium, cobalt) [Ru2Co(~3-O)(I.I,-CH3CO2)6L 3] (L = H20, Py) complexes have been prepared. EPR studies at 77 K show that there is no interaction between the ruthenium and cobalt ions. The ground state of high-spin cobalt is a spin doublet and the two ruthenium ions are antiferromagnetically coupled. IR data show two different types of acetate groups bridging the trinuclear system and the absence of threefold symmetry. ESCA results reveal that the central ix3-oxo bridge is highly covalent and there is no interaction between the ruthenium and cobalt ions.

## Abstract The reductive carbonylation of ruthenium and osmium halides in the presence of cobalt and iron surfaces was studied. In these surface‐assisted reactions the metal surface plays an active role in releasing metal ions, which can be used for the in situ synthesis of mixed‐metal compounds.
