Novel C–H activation in a bis-tetrairidium carbonyl complex of the sandwich compound [Fe(η5-C5H5)(η5-P3C2But2)]: crystal and molecular structures of [Ir4(CO)11{Fe(η5-C5H5)(η5-P3C2But2)}] and [HIr4(CO)10-{µ-Fe(η5-C5H5)(η5-P3CH2(CMe2)CBut)}Ir4(CO)11]

Abstract

The syntheses and structural determinations of novel complexes of the type [Ir₄(CO)₁₁L]{L =[Fe(η⁵-P₃C₂Bu^t₂)(η⁵-P₂C₃Bu^t₃)] or [Fe(η⁵-C₅H₅)(η⁵-P₃C₂Bu^t₂)]} and [HIr₄(CO)₁₀-{µ-Fe(η⁵-C₅H₅)(η⁵-P₃CH₂(CMe₂)CBu^t)}Ir₄(CO)₁₁], involving an unusual C–H activation, are described.
