Abstract
A dinuclear Co complex with bis(pyridyl)pyrazolato (bpp-) and terpyridine (trpy) ligands, [CoIII2(trpy) 2(μ-bpp)(OH)(OH2)]4+ (14+), undergoes three-electron reduction by cobaltocene in acetonitrile to produce 1+, which is in the protonation equilibrium with the Co IICoIII-hydride complex, and the further protonation of the hydride by trifluoroacetic acid yields hydrogen quantitatively. The kinetic study together with the detection of the CoIICoIII-hydride complex revealed the mechanism of the hydrogen production by the reaction of 1+ with trifluoroacetic acid.
