Probing the structure of gas-phase metallic clusters via ligation energetics: sequential addition of C2H4 to Agm+ (m=3-7)

J Am Chem Soc. 2005 Jul 20;127(28):9994-5. doi: 10.1021/ja052251j.

Abstract

A new method that utilizes ligation to probe geometries of clusters in the gas-phase has been developed. This technique bases structural assignments on thermodynamic quantities obtained for sequential ligand additions to a bare cluster. The information is obtained from temperature-dependent equilibrium data. This method is also sensitive to changes in bare cluster conformations that occur as a result of ligand addition, and the results can be fine-tuned by choosing ligands that appropriately adjust cluster-ligand binding energies.
