Talk:Group 14 hydride

Bond lengths

Looking at the two tables, in the Bond Length columns, only 3 of the 9 rows have bond lengths listed. Either these bond lengths should be added, or the columns titled differently. — Preceding unsigned comment added by Dtemp (talk • contribs) 17:40, 10 September 2020 (UTC)[reply]

Flerovium derivatives notable?

As far as I know, we don't know much about the chemistry of flerovium, except that it may not follow expected trends from its lighter homologues because of strong relativistic effects. In particular, the oxidation states +/-4 are predicted to be highly unstable and only possible in a few compounds, like FlF₄. So the existence of FlH₄ and Fl₂H₆ is highly speculative.

By the way, the similar entry about Moscovium hydride (McH₃) has been removed from the Pnictogen hydride article, although for this compound there are a few calculations available which seem to indicate that this compound is possible. Flevorium hydrides, in comparison, are even more obscure as their existence is very uncertain. Perhaps a FlH₂ exists, but that would formally be a carbene derivative.

(Obviously, any such compounds of super-heavy elements are of purely academic interest. But if there aren't even any sources claiming that a compound may exist, it becomes pretty superfluous to mention it.) 2001:41B8:83F:4250:0:0:0:BA (talk) 18:55, 2 August 2023 (UTC)[reply]
