Abstract

L-penicillamine (L-pen) ligands are incorporated in similar pentanuclear Au'₃M₂ (M = Ni¹¹, Co¹¹¹) 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.
