Same but different : L ‐Cysteine ( L ‐cys) and L ‐penicillamine ( L ‐pen) ligands are incorporated in similar pentanuclear Au I 3 M 2 (M=Ni II , Co III ) structures with, however, opposite stereochemical configurations. This phenomenon is explained in terms of intramolecular hydrogen bonding and steric interactions, which may provide insight into why D ‐penicillamine behaves like L ‐cysteine in nature.
