Inclusion compounds

Example of an inclusion compound (a cucurbituril )

In chemistry, inclusion compounds refer to complexes in which a component (the host) forms a cavity or, in the case of crystals, gaps in the crystal lattice in the form of long tunnels or channels. A guest molecule is housed in these spaces. There are no covalent bonds between guest and host . The attraction is mainly due to Van der Waals forces . If the guest is surrounded on all sides by the host lattice, as in a cage, one speaks of cage inclusion compounds or clathrates .

The chemical industry uses urea inclusion compounds in urea extractive crystallization to separate n- and iso- paraffins to lower the pour point of lubricating oils .
