“…The yellow or yellow-green intercalates of the composition VOPO 4 ÁxC n H 2n?1 NH 2 (n = 1-10, x = 1.68-2.02) were obtained by the direct reaction of anhydrous vanadyl phosphate and aliphatic amines [116]. The basal spacing increases by about 1.4 Å by lengthening the chain from n(even) to n ?…”

“…The reaction of VOPO 4 Á2H 2 O with 4-butylaniline yielded intercalation compounds with formula VOPO 4 ÁnH 2 OÁ xC 4 H 9 C 6 H 4 NH 2 (x = 1.2-2.3, depending on the reaction time) which can be exfoliated in tetrahydrofuran [116,126]. Intercalation compounds of N-methylaniline, 2-ethylaniline and 2-propylaniline containing both monomer and polymer species were prepared [127].…”

The intercalation chemistry of layered a I modification of vanadyl phosphate and vanadyl phosphate dihydrate is reviewed. The focus is on neutral molecular guests and on metal cations used as guest species. The basic condition for the ability of the neutral molecules to be intercalated into vanadyl phosphate is a presence of an electron donor atom in them. The most commonly used guest compounds are those containing oxygen, nitrogen or sulfur as electron donor atoms. Regarding the molecules containing oxygen, various compounds were used as molecular guests starting from water to alcohols, ethers, aldehydes, ketones, carboxylic acids, lactones, and esters. An arrangement of the guest molecules in the interlayer space is discussed in connection with the data obtained by powder X-ray diffraction, thermogravimetry, IR and Raman spectroscopies, and solid-state NMR. In some cases, the local structure was suggested on the basis of quantum chemical calculations. Besides of those O-donor guests, also N-donor guests such as amines, nitriles and nitrogenous heterocycles and S-donor guests such as tetrathiafulvalene were intercalated into VOPO 4 . Also intercalates of complexes like ferrocene were prepared. Intercalation of cations is accompanied by a reduction of vanadium(V) to vanadium(IV). In this kind of intercalation reactions, an iodide of the intercalated cation is often used as it serves both as a mild reduction agent and as a source of the intercalated species. Intercalates of alkali metals, hydronium and ammonium were prepared and characterized. In the case of lithium and sodium intercalates, a staging phenomenon was observed. These redox intercalated vanadyl phosphates undergo ion exchange reactions which are discussed from the point of the nature of cations involved in the exchange. Vanadyl phosphates in which a part of vanadium atom is replaced by other metals are also briefly reviewed.

“…sufficient amounts of the guest molecules, the chains in the intercalate possess the all-trans configuration (1,18) and their axes form either an acute angle (usually 55-60°) (11,16) or a right angle (1,13,14,17) with the host layers. The arrangement of the guest molecules in the interlayer space of the host is most often bimolecular (10,14,17).…”

“…Nitrogen-and oxygencontaining organic molecules form two main groups of such guests. Amines (3,4), carboxamides (5), amino acids (6), and heterocycles (7,8) can be anchored to the layers by a V}N donor}acceptor bond. Aliphatic alcohols (9,10), diols (9,11,12), and polyols (13), carboxylic acids (14), and ketones (15,16) represent the guests which are coordinated to the vanadium atom of the host layers by oxygen.…”
