Abstract
The synthesis and chemical behaviour of the new iron-rhodium anionic carbonyl clusters [Fe2Rh(CO)x]- ( x = 10 or 11) [FeRh4CO)15]2-, [Fe2Rh4(C0)16]2-, and [FeRh5(CO)16]- are reported. Low-temperature multinuclear n.m.r. studies (l3C, 13C-(103Rh}, and l03Rh) on the penta- and hexa-nuclear clusters allow their structures in solution to be unambiguously established and their fluxional behaviour has been investigated through variable-temperature measurements. None shows rearrangement of the metal polyhedron.
