A combined experimental;and computational investigation of the CO dissociation properties of three [Fe]-hydrogenase models, [(2-CH2CO-6-HOC5H3N)Fe(CO)(3)I] (1), [(2-CH2CO-6-MeOC5H3N)Fe(CO)(3)I] (2), and [(2-CH2CO-6-tBuOC(5)H(3)N)Fe(CO)(3)I] (3), shows equilibria of tricarbonyl and dicarbonyl complexes in solution. In CH3CN, 1 transforms to the solvated product [(2;CH2CO-6-HOC5H3N)Fe-(CO)(2)(CH3CN)I] (7). The reactivity of 2 with PPh3 was also explored; giving [(2-CH2CO-6,MeOC5H3N)Fe(CO)(2)(PPh3)I] (8) via, one CO substitution by PPh3.
