Wrong substance identified in chembox

Should this be C21H19O2 with smiles of COC1=CC=C(C=C1)[C](C2=CC=CC=C2)C3=CC=C(C=C3)OC as the central carbon is a radical without hydrogen attached? Or is it a cation with smiles COC1=CC=C(C=C1)[C+](C2=CC=CC=C2)C3=CC=C(C=C3)OC Graeme Bartlett (talk) 01:30, 4 May 2022 (UTC)[reply]

​There IMHO should not be chembox at all, since functional group is not a real chemical individuum. —Mykhal (talk) 20:22, 14 November 2022 (UTC)[reply]
But it does exist as an separate substance according to the article. PubChem takes this to have hydrogen and calls it "4,4'-Benzylidenedianisole"[1] Wikidata[2] has a substance with hydrogen, but calls it a "cation". Graeme Bartlett (talk) 21:05, 14 November 2022 (UTC)[reply]
Mykhal, I agree, the whole chembox should be taken down, and it should just be a figure like the wiki article on Boc or Fmoc. — Preceding unsigned comment added by 50.228.101.246 (talk) 16:29, 2 May 2023 (UTC)[reply]
After just checking your edits, Mykhal, I see that you've been here plenty long enough  – much longer than I have – to know all I say below. Sorry to patronize you here; I'm leaving it up for anon's sake. Bernanke's Crossbow (talk) 08:19, 7 June 2023 (UTC)[reply]
​Mykhal & anon: There is long-standing consensus that {{Chembox}} should be used for ions as well as molecules, and the reasoning presumably applies to radicals as well. Written documentation of the practice is rather thin, but does exist.[1] The last comments proposing to do otherwise occurred at least a decade ago,[2] but there (I think) some merit to the idea: chemboxen are inappropriate for families of compounds, and the boundary between a common ion and its family of salts can prove rather thin.[3] The current choice enables consistency with our treatment of charged pharmaceuticals, whose articles are at the proprietary name of the active ion, not the formulation-variant neutral salt,[4] but still deserve a chembox. If you want to modify the consensus, you should probably reopen discussion over at WP:CHEM. Bernanke's Crossbow (talk) 08:13, 7 June 2023 (UTC)[reply]
