摘要：

Vanadyl organophosphonates of general formula VO(RPO3)•xH2O•yC2H5OH have been synthesized by the reaction of V2O5 with RPO3H2 in refluxing ethanol (R = 1-naphthyl, 2-naphthyl, benzyl, p-chlorobenzyl, p-methylbenzyl, p-methoxybenzyl, α-methylbenzyl, 2,5-dimethylbenzyl, p-teri-butylbenzyl, benzoylmethyl, 1-naphthylmethyl, and 2-naphthylmethyl) and characterized by thermogravimetric analysis and X-ray powder diffraction. The new compounds exhibit layered structures that can be divided into groups according to the layer spacings observed. Benzylphosphonic, (p-chlorobenzyl)phosphonic, 2-naphthylphosphonic, and (benzoylmethyl)phosphonic acids form vanadyl compounds with structures in which the organic groups from adjacent layers interpenetrate, resulting in relatively small layer spacings, while the rest of the new compounds have structures in which the organic groups from adjacent layers abut, forming bilayers. Butanols undergo intercalation reactions resulting in expansion of the interlayer distance only in the former compounds, which possess layers of interdigitating organic groups. © 1990, American Chemical Society.
