A new N , N′ ‐bis(triptycenyl)‐NHC ligand with methyl groups in the ortho position has been synthesized starting from 2,3‐dimethyltriptycene‐1,4‐quinone. The respective metal complexes [ML(NHC)] [ML = CuBr, AuCl, PdCl(allyl), RhCl(cod), IrCl(cod), RhCl(CO) 2 , IrCl(CO) 2 , and RuCl 2 (=CHC 6 H 4 O i Pr)] were obtained by standard procedures. All the complexes were initially mixtures of syn and anti isomers. The ruthenium complex was separated into the syn and anti isomers. The crystal structure of the anti complex [RhCl(cod)( 8 )] has been determined.
