Oxo-centred triruthenium formate complexes. Diphosphine adducts of oxo-centred triruthenium acetates

Abstract

Early studies by Mond have been repeated and the oxo-centred formate [Ru3O(O2CH)6(OH2)3][O2CH] obtained. Like its acetate analogue this undergoes a reversible one-electron reduction. It reacts with pyridine (py) to give Ru(O2CH)2(py)2 and Ru(O2CH)2(py)4 and with carbon monoxide to give [Ru3O(O2CH)6(OH2)2(CO)]. A sodium salt, Na[Ru(O2CH)3(OH2)], has also been isolated. Interaction of bis(diphenylphosphino)methane (dppm) and 1,2-bis(diphenylphosphino)ethane (dppe) with [Ru3O(O2CMe)6(MeOH)3]0.1+ gives the acetatobridged dicationic species [Ru2(O2CMe)4L2][ClO4]2. Neutral species, Ru2(O2CMe)4(dppm)2, Ru(O2CMe)2(dppm)2, and probably Ru6O2(O2CMe)12(dppe)3 have been isolated.
