摘要: According to low-temperature UV-Vis spectroscopy data, the two-step protonation of iron subgroup metal hydrides [{P(CH2CH2PPh2)3}MH2] (M = Fe, Ru, Os) with p-nitrophenol includes formation ion pairs stabilized by a hydrogen bond between cationic dihydrogen complex and phenolate anion. The trend extent proton transfer appeared be aperiodic, FeI ≪ OsI < RuI, in contrast previously obtained sequence proton-acceptor capacity hydride ligand, which increases down group.
