Abstract

Gas-phase core electron binding energies have been determined for [Fe(CO)₄]₂CH₂, [CpMn(CO)₂]2CH₂, (CpCoCO)₂CH₂, (CpRhCO)₂CH₂, and several structurally related compounds. The binding-energy data indicate that the CH₂ groups in the μ-CH₂ complexes are highly negatively charged, especially in the manganese, cobalt and rhodium compounds. Data for Fe(CO)₄C₂H₄ indicate that the CH₂ groups in this compound are negatively charged but less so than in the μ-CH₂ compounds. Data for Fe₃(CO)₁₂ suggest the presence of both terminal and bridging carbonyl groups.
