We report the synthesis of a series of chiral heterobimetallic complexes of the type [R = (η6-arene)Cr(CO)3, R‘ = H or R = H, R‘ = (η6-arene)Cr(CO)3] and one X-ray structure. All new complexes react with MeI, affording the analogous cationic complexes and the diamagnetic NMR chiral shift reagent TRISPHAT anion has been used to differentiate the enantiomers of a selected complex in solution.
