Abstract

The electronic structure of H₂M₃(CO)₉S clusters (M = Ru, Os) is discussed on the basis of their He I and He II excited gas-phase photoelectron spectra and on the basis of CNDO quantum mechanical calculations. The PE data clearly demonstrate the cleavage of two direct MM interactions by operation of the bridging hydrides, giving rise to three-center two-electron MHM levels. The μ₃-S bonding mode has been described in detail and compared with previous results on related μ₃-CY cluster derivatives. The CNDO results on Ru₃(CO)₉S⁼, HRu₃(CO)₉S^- and H₂Ru₃(CO)₉S indicate that the μ₃-S-cluster interaction is mostly independent of the presence of the bridging hydrides.
