- W1977984941 abstract "The gas-phase reactions of Mn(CO)−4 with CO and 13CO are reported. Only addition was observed with CO producing Mn(CO)−5 (kapp = (2.5±0.2) × 10−12 cm3 molecule−1 s−1). Both addition (kadd = (3.2 ±0.4) × 10−12 cm3 molecule−1 s−1) and substitution (ksub = (1.2 ± 0.4) × 10−12 cm3 molecule−1 s−1) product-forming channels were observed in the reaction with 13CO. The average branching fractions for addition and thermoneutral substitution are 0.74 and 0.26 respectively. These branching fractions and the 70% collisional quenching efficiency of the excited addition intermediates [Mn(13CO)(CO)−4]★ with the helium buffer gas are essentially the same values as those previously obtained for the quenching/decomposition of [Fe(13CO)(CO)−3]★. The ground electronic state of Mn(CO)−4 is believed to be the triplet because the negative ion is isoelectronic with Fe(CO)4, a known ground state triplet complex. Thus, the slow rate of the Mn(CO)−4/CO reaction (reaction efficiency = 0.0036) is considered to be the result of the spin-forbidden curve crossing of the triplet Mn(CO)−4 + CO inlet surface to the attractive singlet Mn(CO)−4 + CO → singlet Mn(CO)−5 product surface. Comparisons with the results from the fast spin-allowed addition/substitution reactions of Fe(CO)−3 with 13CO are given." @default.
