We report a joint photoelectron spectroscopy and theoretical investigation of the gaseous Au<sub>2</sub>I<sub>3</sub><sup>-</sup> cluster, which is found to exhibit two types of isomers due to competition between Au-I covalent bonding and Au-Au aurophilic interactions. The covalent bonding favors a bent IAuIAuI<sup>-</sup> structure with an obtuse Au-I-Au angle (100.7°), while aurophilic interactions pull the two Au atoms much closer, leading to an acutely bent structure (72.0°) with an Au-Au di ...[more]
