from which only 7 can be isolated in a pure state. Protonation of 4 by HPF6 yields the cationic hydridoruthenium(II) complex [RuH(η4-1,5-COD)(η6-phenanthrene)]PF6, [5]PF6, in 53% yield, whereas similar protonation of 7 gives an equilibrium mixture of a hydrido diene complex [RuH(η4-1,5-COD)(η6-9,10-dihydroanthracene)]PF6, [8]PF6, and an agostic cyclooctenyl complex [Ru(η1,η3-C8H13)(η6-9,10-dihydroanthracene)]PF6
