The dd/ll and meso isomers of commo-ferracarborane [Ph₃PR][commo-1,1′-Fe(closo-2,4-C₂B₈H₁₀)₂], with closo geometry, were obtained and their structures determined. Facile dd/ll meso and meso dd/ll transformations occur in solution and DFT calculations of the interconversions were performed. Ferra–copper zwitterionic complexes of each isomer were synthesized and their structures determined.
