The preparation and X-ray structural investigation of the three stoichiometric host-guest compounds 1 * 2 H2O, 2 * xylene and 3 * 3 dioxane, is described.Whereas the tetralactame cryptand host 1 with water forms hydrogen bridges using its carbonyl oxygen atoms, leading to chain type arrangement in the crystal, the para-xylene adduct of cryptand 2 and the dioxane adduct of the tetraazaphane 3 both are channel type inclusions of the guest molecules in the host lattice.It is concluded that even if an approximate geometric fit of a guest to the host cavity is given, the alternative of a lattice inclusion nevertheless may be favoured.
