Talk:Caesium auride

Using only EN values and electron affinities, HAu should exist.

H has EN=2.20 and EA=73 kJ/mol, and Au has EN=2.54 and EA=223 kJ/mol. 80.98.179.160 (talk) 19:47, 22 March 2018 (UTC)[reply]

Gold hydride is actually an interstitial compound, as the small H atoms fit in between the large Au atoms in their crystal structure; interestingly it has the crystal structure of Hg, which fits quite well with the electrons on H half filling the d-band and half filling the s-band of Au. Anyway, the difference in electronegativity between H and Au is not so high that the compound could reasonably be expected to be ionic (consider covalent CF₄). You may nevertheless be interested in high-pressure Au compounds with Au in even more negative oxidation states filling up the 6p orbitals. Double sharp (talk) 02:34, 23 March 2018 (UTC)[reply]
