Mechanistic study of the photofragmentation of the clusters [Os3(CO)10(diene)] (diene=cis-1,3-butadiene, 1,3-cyclohexadiene): direct observation of the open-triangle primary photoproduct with nanosecond time-resolved infrared and UV–Vis spectroscopy

The fragmentation was studied further with nanosecond time-resolved UV–Vis and IR spectroscopy and was found to proceed via the initial formation of a triosmium photoproduct with a lifetime of about 100 ns in hexane. From the spectroscopic data we infer that this intermediate has a coordinatively unsaturated open-triangle structure with two bridging carbonyl groups, one bridging the split (CO) 4 OsOs(CO)
