|Title:||Fibrous Cerium (iv) Acid Phosphates Host Of Weak And Strong Lewis Bases|
|Abstract:||In this paper, we evaluated the behavior of fibrous cerium (IV) acid phosphate (CeP) in insertion procedures involving a strong Lewis base (ethylamine) and a weak one (ε-caprolactam). In the former case, the procedure was performed by exposing a sample of CeP to a saturated amine atmosphere. Insertion was shown to be independent of the crystallinity of CeP, and the products showed strong host-guest interactions of the Coulombic type. Conversely, ε-caprolactam insertion was achieved by immersing CeP samples into its fused form. This process was dependent on the crystallinity of the inorganic solid, and host-guest interactions were characterized as involving hydrogen bonds. © Springer 2005.|
