Abstract The formations of molecular nitrogen and hydrogen complexcs (η6-C6H6)Cr(CO)2 L(L = N2 and H2) were observed via time-rcsolvcd infrarctd spectroscopy following 3%nm laser photolysis of (η6-C6H6)Cr(CO)3 in the presence of N2 and H2 in gas phase. The rate constants for reactions of (η6-C6H6) Cr(CO)2 with N2 and H2 were measured to be ( 1.4 ±0.1 ) x 105 Torr-1s-1 and ( 2.6 ±0.1) x 105, Torr-1s-1, respectively. The complexes(η6-C6H6)Cr(CO)2 (L = N2 and H2) have lifetimes longer than 1 ms in our experimental conditions implying the N2 and H2 binding energies in (η6-C6H6)Cr(CO)2 L (L = N2 and H2) >17 kcal mol-1.
