Abstract

Previous studies have found that gold atom and boronyl bear similarities in bonding in many gas phase clusters.\footnote{H.-J. Zhai, C.-Q. Miao, S.-D. Li, L.-S. Wang, J. Phys. Chem. A 2010, 114, 12155–1216}\ \footnote{Q. Chen, H. Bai, H.-J. Zhai, S.-D. Li, L.-S. Wang, J. Chem. Phys. 2013, 139, 044308}\ \footnote{H. Bai, H.-J. Zhai, S.-D. Li, L.-S. Wang, Phys. Chem. Chem. Phys., 2013, 15, 9646–9653}\ \footnote{H.-J. Zhai, Q. Chen, H. Bai, S.-D. Li, L.-S. Wang, Acc. Chem. Res. 2014, 47, 2435-2445}\ B$_{10}$(BO), B$_{12}$(BO), B$_{3}$(BO)$_{n}$ (n=1, 2) were found to possess similar bonding and structures to B$_{10}$Au, B$_{12}$Au, B$_{3}$Au$_{n}$ (n=1, 2), respectively. During the recent photoelectron spectroscopy experiments, the spectra of BiBO$^{-}$ and BiAu$^{-}$ clusters are found to exhibit similar patterns, hinting that they possess similar geometric structures. While BiAu$^{-}$ is a linear molecule, BiBO$^{-}$ is also linear. The similarity in bonding between BiBO$^{-}$ and BiAu$^{-}$ is owing to the fact that Au and BO are monovalent $\sigma$ ligands. The electron affinities are measured to be 1.79$\pm$0.04eV for BiBO$^{-}$ and 1.36$\pm$0.02eV for BiAu$^{-}$. The current results provide new examples for the BO/Au isolobal analogy and enrich the chemistry of boronyl and gold.\\
