Layered vanadyl organophosphonates of general formula VO(RPO3) · nH2O, where R = CH3, C2H5, C6H5, were synthesized in alcoholic solution. Intercalation of alkanols, CnH2n+1OH (n = 1 - 4), and benzyl alcohol with each phosphonate previously prepared is reported and discussed. Samples and intercalation compounds were characterized for their X-ray powder diffraction patterns, IR spectra, and TGA analyses

Synthesis of vanadyl(IV) organophosphonates VORPO(3) . nH(2)O (with R = CH3, C2H5, C6H5) has been investigated by reaction of VOSO4 . 5H(2)O + RPO(3)H(2) under refluxing conditions in aqueous media. The influence of different parameters is discussed, and compounds are characterized by X-ray powder diffraction, TGA, IR, XANES, and EXAFS. For example, three crystallographic forms of VOC6H5PO3 .2H2O obtained differ from each other in the location of the trans water molecule in the layered structure.

Layered vanadyl organophosphonates VORPO(3) . xH(2)O were brought into contact with primary alkylamines CnH2n+1NH2 (n = 3-6). Intercalation compounds have been characterized by their basal spacings, thermogravimetric analysis (TGA), XANES, and IR spectra. Regardless of the starting vanadyl phosphonate, a plot of the interlayer distances of the intercalates vs the number of carbon atoms (n(c)) in the alkyl chain of the amine indicates that amine molecules were packed in the interlamellar space either as bilayer or as an interdigitated monolayer, depending on n(c). Hydrolysis of the phosphonate groups, oxidation of vanadium atoms, and the nature of the final products are described.
