Oxidative-addition of the N-H bond of saccharin (sacH) to a triosmium centre: Synthesis, structure and reactivity of Os3(CO)10(μ-H)(μ-sac)

The triosmium cluster Os3(CO)10(μ-H) (μ-sac) has been synthesized from the reactions between Os3(CO)10-n(NCMe)n (n = 1, 2) and saccharin (sacH). Its reaction with various monodentate phosphines, PR3 (R = Ph, Th, Fu), has also been investigated.
