Structure Bonding of the Gold-Subhalide Cluster I-Au144Cl60z

摘要

The structure and bonding of the gold-subhalide compounds Au144Cl60^[z] are related to those of the ubiquitous thiolated gold clusters, or Faradaurates, by iso-electronic substitution of thiolate by chloride. Exact I-symmetry holds for the [z] = [2+,4+] charge-states, in accordance with new ESI-MS measurements and the predicted electron shell filling. The High symmetry facilitates analysis of the global structure as well as the bonding network, with some striking results.
