In that framework multicentre bonds do not exist. So hypercoordination is indeed a better term for what is at play here. Even though it is used as a synonym often, I would actually advise against this. However, you can easily substitute the latter for any intends and purposes. | |

| Dec 2, 2022 at 23:03 | comment | added | iwab | @Andrew Maybe I should consider hypervalency as a synonym for hypercoordination? | |
| Dec 2, 2022 at 22:52 | comment | added | iwab | @Andrew Or more precisely, are there really any that are truly hypervalent? ch.imperial.ac.uk/rzepa/blog/?p=2599 | |
| Dec 2, 2022 at 22:41 | comment | added | iwab | @Andrew Thank you! Btw. what do you mean by "whether or not they are truly hypervalent"? Are there compounds that are/ aren't truly hypervalent? | |

| Dec 2, 2022 at 13:34 | comment | added | Andrew | Lewis structures are not intended to be accurate representations of the electronic structure of molecules. They follow conventional rules that make the drawings simple, but informative. According to those conventions, expanded octets are preferred in the drawing for elements larger than fluorine, whether or not they are truly hypervalent. | |

Interposed question, in which orbitals are the three lone pairs at the xenon atom?
