The photochemistry of (Me3P)(OC)4OsW(CO)5 (1), a molecule with a dative covalent metal−metal bond, was investigated. The results indicate that the photoprocess is heterolytic cleavage of the metal−metal bond, rather than homolytic cleavage as is

High-resolution variable-energy photoelectron spectra of Os(CO)5 and Os(CO)4PMe3 are reported. Using variable-energy synchrotron radiation, both the metal 5p → 5d resonance and the Cooper minimum effect are observed on the osmium 5d orbitals, and t
