Implication

Experimental study demonstrates preferential bis-ligand formation in atomic gold ion complexes, indicating covalent dumbbell stabilization.

Key Points

To investigate the synthesis, complex stoichiometry, and ionization-induced fragmentation patterns of atomic gold ions paired with diverse atomic and molecular ligands.
Passed helium nanodroplets sequentially through two pickup cells containing gold vapor and selected ligand dopants (rare gases, diatomics, or polyatomic molecules).
Irradiated the doped nanodroplets with electrons to induce ionization.
Identified product cations and anions using a high-resolution mass spectrometer.
Abundance distributions for most AuLn+ complexes exhibited a pronounced peak at n = 2, confirming preferential bis-ligand formation characterized by covalent L-Au+-L dumbbell configurations.
Gold ions generally enhanced ionization-induced intramolecular fragmentation across most ligand systems relative to pure ligand clusters.
Complexation with gold suppressed intramolecular fragmentation in Au(H2)n+ by an order of magnitude compared to pure (H2)n+ clusters.
