Gold is isolobal to hydrogen. Despite the fact that Au and Si do not form stable alloys, Si and Au form stable covalently bounded clusters, as evidenced from anion photoelectron spectroscopy and ab initio calculations. In a series of [SiAun] clusters (n=2–4) that are similar to SiHn (n=2–4) in structure, chemical bonding, and stability, Au atoms are shown to be isolobal to hydrogen atoms (see picture).
