Talk:Beryllium chromate

BeCrO₄

There is some information on The Materials Project. Also, BeCrO₄·H₂O is known. It crystallizes as monoclinic reddish yellow crystals, which is decomposed by water to form a yellow basic salt (ref).--Leiem (talk) 07:49, 21 April 2023 (UTC)

Where does "The Materials Project" get their information from? Is is purely computational and not based on any publication? (I am suspecting an unreliable source). So far I have not been able to view "the chemical news" from 1907. But I have not given up yet. A basic salt might also explain some of those German references that come up with weird compositions.

I didn't find the information source of "The Materials Project". Some computational papers reported noble gas binding ability of BeCrO₄ (doi:10.1039/C6RA20232B; doi:10.1039/D0CP04912C). And one more ref here.--Leiem (talk) 18:05, 21 April 2023 (UTC)

Delete: "The Materials Project" explicitly states that this compound has never been experimentally observed. All the other references are computations. The one that shows experimental evdience only shows the existence of Be(HCrO₄)(OH), a basic chromate. Keres🌕Luna ^edits! 16:31, 26 April 2023 (UTC)

@Leiem: The source that you referenced is very old and is not supported with diffraction or crystallographic data. Such sources are insufficient evidences of existence. Keres🌕Luna ^edits! 16:38, 26 April 2023 (UTC)

• Keep - Correct me if I'm wrong but materials don't have to have been observed in a laboratory or whatever to be notable. Wikipedia notbality criteria is based on coverage of the subject (in whatever form it takes) in reliable sources. I believe that threshold is met. ~Kvng (talk) 13:10, 29 April 2023 (UTC)
