Observation of localised CO exchange mechanisms at the iron and ruthenium centres of di-µ-carbonyl (Fe : Ru2, Ru3)-di-µ-hydrido (Ru1 : Ru2, Ru3)-tetrahedro-tris(tricarbonylruthenium)dicarbonyliron(3Fe–Ru, 3Ru–Ru) by 13C n.m.r spectroscopy

Abstract

Variable temperature ¹³C n.m.r. studies show that [H₂FeRu₃(CO)₁₃] is undergoing intramolecular carbonyl exchange in three distinguishable stages: the first localised at iron; the second localised at the three rutheniums; and the last general over all metal centres.
