Chiral and Achiral Crystal Structures of Au (PET) Reveal Effects of Ligand Rotational Isomerization on Optoelectronic Properties.

The crystal structures of 4 ligand-rotational isomers of Au (PET) are presented. Two new ligand-rotational isomers are revealed, and two higher-quality structures (allowing complete solution of the ligand shell) of previously solved Au (PET) clusters are also presented. One of the structures lacks an inversion center, making it the first chiral Au (SR) structure solved.

Gold nanoclusters show distinctive magnetic properties and electronic structure. Nanoclusters of sufficiently small size restructure geometrically to stabilize electronically (e.g.
