Structures, Interconversions, and Spectroscopy of Iron Carbonyl Clusters with an Interstitial Carbide: Localized Metal Center Reduction by Overall Cluster Oxidation.

ABSTRACT: The syntheses, interconversions, and spectroscopic properties of a set of iron carbonyl clusters containing an interstitial carbide are reported. This includes the low temperature X-ray structures of the six-iron clusters (Y)₂[Fe₆(μ₆-C)(μ₂-CO)₄(CO)₁₂] (1a-c; where Y = NMe₄, NEt₄, PPh₄); the five-iron cluster [Fe₅(μ₅-C)(CO)₁₅] (3); and the novel formulation of the five-iron cluster (NMe₄)₂[Fe₅(μ₅-C)(μ₂-CO)(CO)₁₃] (4). Also included in this set is the novel charge-neutral cluster, [Fe₆(μ₆-C)(CO)₁₈] (2), for which we were unable to obtain a crystallographic structur
