摘要：

The synthesis and structural aspects of urea host-guest inclusion compounds containing linear secondary alkylamines (dibutyl-, dipentyl-, dihexyl-, dioctyl-) at 25 degrees C are reported. Elemental analysis, C-13 CP-MAS NMR and H-1-NMR Spectroscopy, and Powder X-ray Diffraction Analysis confirm the inclusion process. The basic host structure of the products is similar to that of urea-hydrocarbon systems. C-13 MAS-NMR experiments show chemical shift differences for the confined guest molecule with respect to, the liquid phase. Stoichiometry and \c(g)\ values for the inclusion compounds with dipentyl- and dihexylamine suggest a commensurate structure.
