Feel the pinch! Planar–chiral, cationic, ruthenium–palladiumcomplexes based on η6,η1‐coordinated ECE′ pincerligands are synthesized as racemic mixtures by reacting ECE′–palladium complexes and [Ru(C5R5)(MeCN)3]+ arenophiles (R=H or Me). Chiral resolution of the cationic complexes was achieved by using the chiral counterion [Δ‐TRISPHAT]−, and solving the X‐ray crystal structure of one diastereoisomer
