The photochemistries of Mn2(CO)10 and Re2(CO)10 following excitation at 337 nm in the region of their σ⋆ ← σ bands are investigated under collision-free conditions. Results suggest that in addition to the M(CO)5 photofragments previously reported in the molecular beam study of Freedman and Bersohn, partially decarbonylated dimetal photofragments are also produced. Thus, in the gas phase, as in solution, both dissociative CO loss and M-M bond scission appear to be primary photochemical processes in the dimetal decacarbonyl systems.
