Intercalation of esters into vanadyl phosphate

Intercalates of vanadyl phosphate with formates and acetates of C1–C8 alcohols and dimethylesters of dicarboxylic acids C2–C6 were prepared by a displacement reaction of 2-propanol-intercalated VOPO4. The diffractograms of the intercalates show a series of sharp (0 0 l) reflections, (2 0 0) reflection and in some cases several (h k l) lines with low intensity. The tetragonal lattice parameters of the intercalates were calculated. The intercalates prepared are not stable in air. The C=O stretching vibration in IR spectra of the intercalates prepared was shifted to lower wavenumbers in comparison with the spectra of the pure guests, indicating that all esters are anchored to the host layers by their carbonyl oxygen.
