Spectroscopic X-ray and Mossbauer Characterization of M₆ and M₅ Iron(Molybdenum)-Carbonyl Carbide Clusters: High Carbide-Iron Covalency Enhances Local Iron Site Electron Density Despite Cluster Oxidation.

ABSTRACT: The present study employs a suite of spectroscopic techniques to evaluate the electronic and bonding characteristics of the interstitial carbide in a set of iron-carbonyl-carbide clusters, one of which is substituted with a molybdenum atom. The M₆C and M₅C clusters are the dianions (Et₄N)₂[Fe₆(μ₆-C)(μ₂-CO)₂(CO)₁₄] (1), [K(benzo-18-crown-6)]₂[Fe₅(μ₅-C)(μ₂-CO)₁(CO)₁₃] (2), and [K(benzo-18-crown-6)]₂[Fe₅Mo(μ₆-C)(μ₂-CO)₂(CO)₁₅] (3). Because 1 and 2 have the same overall cluster charge
