INTERCALATION OF 2-SULFANYLPYRIDINE, 4-SULFANYLPYRIDINE, 2,2'-DITHIOBISPYRIDINE AND 4,4'-DITHIOBISPYRIDINE INTO VOPO4, AND GEL-V2O5 INTERLAYER SPACES

2-(2-Spy) and 4-sulfanylpyridine (4-Spy) have been inserted into the g el-V2O5 interlayer space, accompanied by oxidative S-S coupling, to fo rm intercalation compounds including mostly N-protonated 2,2'-(2,2'-py SSpy) and 4,4'-dithiobipyridine (4,4'-pySSpy) moieties as a guest. 2,2 '-pySSpy and 4,4'-pySSpy were also intercalated into the gel-V2O5 inte rlayer space to yield similar intercalation compounds. 2-Spy, 4-Spy an d 4,4'-pySSpy formed no stable intercalation compounds with VOPO4 soli ds, while 2,2'-pySSpy was inserted into the VOPO4 lattice to afford an intercalation compound with fewer N-protonation sites. X-Ray diffract ion patterns and X-ray photoelectron spectra of the intercalation comp ounds are discussed.
