N2 - The acid-base chemistry of some ruthenium ethyne-1,2-diyl complexes, [{Ru(CO)(2)(eta-C5H4R)}(2)(mu(2)-CdropC](R = H, Me) has been investigated. Initial protonation of [{Ru(CO)(2){eta-C5H4R}}(2)(mu(2)-CdropC)] gave the unexpected complex cation, crystallised as the BF4 salt, [{RU(CO)(2)(eta-C5H4R}}(3)(mu(3)-CdropC)][BF4] (R=Me structurally characterised). This synthesis proved to be unreliable but subsequent, careful protonation experiments gave excellent yields of the protonated ethyne-1,2-diyl complexes, [{Ru(CO)(2){eta-C5H4R)}(2)( mu(2)-eta(1):eta(2)-CdropCH)](BF4) (R=Me structurally characterised) which could be deprotonated in high yield to return the starting ethyne-1,2-diyl complexes.
