Looking for references of two chemical compounds
I'm looking for references of the two substances. Here are some information about them. Does anyone know where to find the references? --Leiem (talk) 16:53, 28 March 2023 (UTC)
 * "Vanadium oxide dimethyl sulfoxide", C2.7H8.1O1.35S1.35.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)
 * 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. C2.7H8.1O1.35S1.35.V2O5 seems to be a vanadium(V) compound. --Leiem (talk) 02:08, 29 March 2023 (UTC)
 * 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? DMacks (talk) 18:05, 28 March 2023 (UTC)
 * Crystallographic properties (such as lattice parameters or crystal structures) and preparation corresponding to the certain structure. --Leiem (talk) 02:08, 29 March 2023 (UTC)
 * @Leiem This paper 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)
