摘要

The formations of molecular nitrogen and hydrogen complexes (η^(6)-C_(6)H_(6))Cr(CO)_(2)-L(L=N_(2) and H_(2))were observed via time-resolved infrared spectroscopy following 355 nm laser photolysis of(η^(6)-C_(6)H_(6))Cr(CO)_(3) in the presence of N_(2) and H_(2) in gas phase.The rate constants for reactions of (η^(6)-C_(6)H_(6))Cr(CO)_(2) with N_(2) and H_(2) were measured to be(1.4±0.1)×10^(5) Torr^(-1)s^(-1) and (2.6±0.l)×10^(5) Torr^(-1)s^(-1),respectively.The complexes (η^(6)-C_(6)H_(6))Cr(CO)_(2)L(L=N_(2) and H_(2))have lifetimes longer than 1 ms in our experimental conditions implying the N_(2) and H_(2) binding energies in (η^(6)-C_(6)H_(6))Cr(CO)_(2)L,(L=N_(2) and H_(2))>17 kcal mol^(-1).
