A @[email protected] in which one component (the @[email protected]) forms a cavity or, in the case of a crystal, a crystal lattice containing spaces in the shape of long tunnels or channels in which molecular entities of a second chemical species (the @[email protected]) are located. There is no covalent bonding between @[email protected] and host, the attraction being generally due to @[email protected] If the spaces in the host lattice are enclosed on all sides so that the @[email protected] species is 'trapped' as in a @[email protected], such compounds are known as @[email protected] or '@[email protected] compounds'.
