Formation and in situ characterization of the first dihydrogen aqua complex: [Ru(H2O)5(H2)]2+
Abstract
The product of the reaction between [Ru(H2O)6]2+ and pressurized H2 in water is [Ru(H2O)5(H2)]2+ whose nature was unambiguously demonstrated by 1H and 17O NMR and which is the first characterized dihydrogen aqua complex.
