Interaction of methanol with a layered α-Sn(IV) phosphate on its surface: A solid-state NMR study

Here, a layered crystalline phosphate, α-Sn(HPO 4 ) 2 ·H 2 O, treated with CD 3 OD was characterized by the 31 P, 119 Sn, 1 H and 2 H solid-state NMR techniques. The 2 H solid-echo MAS NMR spectra of the product have unexpectedly revealed deuterated hydronium ions on the surface of this material instead of intercalated methanol. According to the 13 C NMR and GC–MS studies, these ions are formed by water molecules following a dehydration of the methanol-d 4 to yield deuterated dimethyl ether.
