Intercalation of 2-, 4-sulfanylpyridine, 2,2'- and 4,4'-dithiobispyridine into VOPO4 and gel-V2O5 interlayer spaces

摘要: 2-(2-Spy) and 4-sulfanylpyridine (4-Spy) have been inserted into the gel-V2O5 interlayer space, accompanied by oxidative S–S coupling, to form intercalation compounds including mostly N-protonated 2,2′-(2,2′-pySSpy) 4,4′-dithiobipyridine (4,4′-pySSpy) moieties as a guest. 2,2′-pySSpy 4,4′-pySSpy were also intercalated space yield similar compounds. 2-Spy, 4-Spy formed no stable with VOPO4 solids, while was lattice afford an compound fewer N-protonation sites. X-Ray diffraction patterns X-ray photoelectron spectra of are discussed.
