Decentralized Metal–Metal Bonding in the AuNi(CO)<sub>4</sub><sup>–</sup> Anion Described Equally Well with Dative Bonding as with Electron-Sharing Bonding
The heterodinuclear AuNi(CO)<sub>4</sub><sup>-</sup> complex is scrutinized in the gas phase by using mass-selected anionic photoelectron velocity-map imaging spectroscopy in conjunction with theoretical computations. The ground state of AuNi(CO)<sub>4</sub><sup>-</sup> is characterized to have an Au-Ni bonded structure, consisting of an AuCO fragment attached to the Ni center of the Ni(CO)<sub>3</sub> fragment. Comprehensive quantum chemical studies reveal that the AuNi(CO)<sub>4</sub><sup>-</sup> complex at equilibrium structure features a decentralized bonding scenario, where the exotic metal-metal σ bonding may be equally well described with dative bonding as with electron-sharing bonding between two fragments.
