Hydrogen-Bonded Urea-Anion Host Lattices. 6. New Inclusion Compounds of Urea with Tetra-n-propylammonium Halides

Q. Li and T. C. W. Mak

Synopsis: The novel inclusion complex 2(n-C₃H₇)₄N⁺F^-.7(NH₂)₂CO.- 3H₂O contains a channel framework built from urea ribbons that are bridged by fluoride ions, water molecules and other urea molecules. The complexes (n-C₃H₇)₄N⁺Cl^-.y(NH₂)₂CO (y = 2, 3) feature layer and channel-type urea-chloride host lattices, respectively, whereas the isomorphous compounds (n-C₃H₇)₄N⁺- X^-.3(NH₂)₂CO.H₂O (X = Br, I) exhibit a channel-type host lattice built of corrugated urea layers and centrosymmetric cyclic (H₂O-X^-)₂ units.
