March 28[edit]

Looking for references of two chemical compounds[edit]

I'm looking for references of the two substances. Here are some information about them. Does anyone know where to find the references?

"Vanadium oxide dimethyl sulfoxide", C_2.7H_8.1O_1.35S_1.35^.V₂O₅, PDF card 45-1529
"Lithium benzenesulphonate dihydrate", C₆H₅LiO₃S^.2H₂O, PDF card 46-1724

The first one seems to have some information here. PianoDan (talk) 17:28, 28 March 2023 (UTC)[reply]

Thank you for reply. It is reported that V₂O₅ is reduced by SO₂ in DMSO to form a vanadium(III) complex according to the paper. C_2.7H_8.1O_1.35S_1.35^.V₂O₅ seems to be a vanadium(V) compound. --Leiem (talk) 02:08, 29 March 2023 (UTC)[reply]

SciFinder has 97 refs for CAS No 30215-10-2 ("Benzenesulfonic acid, lithium salt"), but doesn't seem to list the dihydrate specifically. I see some patent literature for it, including synthesis in water as solvent. Could you be more specific what aspects of these chemicals are of interest?

Crystallographic properties (such as lattice parameters or crystal structures) and preparation corresponding to the certain structure. --Leiem (talk) 02:08, 29 March 2023 (UTC)[reply]

@Leiem This paper doi:10.1039/C8CE00224J suggests that it is quite difficult to form stable lithium complexes with simple benzenesulfonates but has several X-ray structures for more exotic ones. I can email you a copy if you don't have access to the full text (contact via my Userpage). In general, if you can find a compound of interest on Pubchem by search here any associated crystal structure will be mentioned in the "Structures" section of their record.

Thank you. I have access to it. Though these benzenesulfonates contain carboxyl groups, the article is a good reference. --Leiem (talk) 17:27, 31 March 2023 (UTC)[reply]
