Abstract

The photoactivation mechanism of Os₃(CO)₁₂ at 400 nm is examined with time-resolved X-ray liquidography. The data reveal two pathways: the vibrational relaxation following an internal conversion to the electronic ground state and the ligand dissociation to form Os₃(CO)₁₁ with a ligand vacancy at the axial position.
