Here, a layered crystalline phosphate, α-Sn(HPO₄)₂·H₂O, treated with CD₃OD was characterized by the ³¹P, ¹¹⁹Sn, ¹H and ²H solid-state NMR techniques. The ²H 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 ¹³C NMR and GC–MS studies, these ions are formed by water molecules following a dehydration of the methanol-d₄ to yield deuterated dimethyl ether.
