It came as a surprise, however, that Aug prefers a trigonal planar D3h structure in the gas phase [16] and is not octahedral as one might assume, suggesting that gold clusters do not follow the usual pattern of typical Lennard-Jones, Morse or Gupta systems, which all favor a maximum number of close atom-atom contacts. The preferred planarity of small gold cluster compounds is due to relativistic effects [17]. [Pg.213]

Several synthetic methods have been employed in the preparation of gold clusters compounds. [Pg.1083]
