The direct reaction of liquid (or melted solid) 1-alkanols or 1,omega-alkanediols with solid finely ground VOPO(4). 2H(2)O in a microwave field leads to layered complexes of the composition VOPO(4).2C(n)()H(2)(n)()(+1)OH (n = 1-18) or VOPO(4).C(n)()H(2)(n)()(OH)(2) (n = 2-10), respectively. The results of X-ray diffraction analysis show that the structures of all of these polycrystalline complexes (intercalates) retain the original layers of (VOPO(4))(infinity). The molecules of alcohols are placed between the host layers in a bimolecular way, being anchored to them by donor-acceptor bonds between the oxygen atom of an OH group and a vanadium atom as well as by hydrogen bonds. The molecules of diols, on the other hand, using similar bonds, form, in monomolecular arrangement, bridges linking the adjacent layers of the host. The aliphatic chains of both intercalated alcohol and diol molecules possess all-trans configurations, and their axes are perpendicular to the host layers.

The structure of the layered αI-VOPO4, VOPO4·2H2O, and their intercalation reactions are discussed. These reactions are divided into two groups. The first includes intercalation reactions of molecular guests which proceed as acid-base processes between the host layered lattice (Lewis acid) and a donor atom of the guest (base). Interaction of water molecules, alcohols, amines, carboxylic acids and their derivatives, heterocyclic N- and S-donors, and complex compounds with vanadyl phosphates is discussed. Vanadyl phosphate, in particular vanadyl phosphate dihydrate can also undergo the second type of the reactions which involves the reduction of a fraction of vanadium(V) atoms to vanadium(IV) with concomitant intercalation of alkylammonium, hydronium or mono- and divalent metal cations to counterbalance the induced negative layer charge.
