摘要：

Niobyl-vanadyl phosphate (V0.14Nb0.86)OPO4.2.7 H2O (NbVP) intercalates n-alkylamine molecules to yield stable layered compounds with high basal spacings and compositions close to 1.7 mole of amine and 2 mole of water per mole of phosphate. The X-ray diffraction, differential thermal analysis, thermogravimetry, and IR and diffuse reflectance spectroscopy (UV-vis-nIR) techniques allow us to establish that the amine molecules are protonated in the interlayer space, where the RNH+3 groups interact with the layers via hydrogen bonds. These amines form a molecular bilayer inclined at 58° with respect to the phosphate layers. © 1990.
