Bimetallic iron–rhodium anionic carbonyl clusters [Fe2Rh(CO)x]–(x= 10 or 11), [FeRh4(CO)15]2–, [Fe2Rh4(CO)16]2–, and [FeRh5(CO)16]–
Abstract
The syntheses and interconversions of mixed iron–rhodium carbonyl clusters are described; a combination of X-ray analysis and multinuclear n.m.r. measurements allowed the structural characterisation of [FeRh4(CO)15]2–, [FeRh5(CO)16]–, and [Fe2Rh4(CO)16]2–, which can all be obtained from the unstable cluster, [Fe2Rh(CO)x]–(x= 10 or 11).
