Structural inconsistency[edit]

doi:10.1021/jm00017a016 identifies this chemical by name as a neutral species with a hydrogen atom on the phosphorus (total H₁₀ in the formula) and ChemSpider agrees. PubChem instead says it is a net cation with no H on P (formula is only H₉). The names vary among "phosphinic acid" and "oxophosphanium" too. What self-consistent substance is the main topic of this article? DMacks (talk) 04:32, 25 March 2021 (UTC)[reply]

It's supposed to be the compound described in Froestl et al. So I got the wrong compound from PubChem. (Interestingly, that PubChem ID links to Froestl et al, whereas PubChem ID 121956, which is C₃H₁₀NO₂P, does not link to any PubMed articles. This is what threw me off when I was trying to find the correct PubChem ID.) I'll go ahead and correct that. proton donor^H⁺ 17:07, 25 March 2021 (UTC)[reply]
