Claihrate compounds

A claihrate compound means, literally, an enclosed compound, a term applied to a solid molecular compound in which a molecule of one component is physically enclosed in the crystal structure of a second compound, so that the properties of the aggregate arc essentially those of the enclosing compound. Examples of such cage compounds" are those of the small molecules of SO . CO.. CO and the noble gases with ice and hydroquinone. which have very open crystal structures. Another example is the claihrate of benzene with nickel cyanide.

There are certain substances formed by combining one stable compound with another or with an atomic or molecular element without the existence of any chemical bonds between the two components. This occurs when one of the compounds can crystallize in a very open structure containing cavities, holes or channels in which atoms or molecules of the other can be trapped. Those compounds in which the host lattice contains cavities like cages are the most important type they are called claihrate compounds, from the Latin... 

The term inclusion compound was once used for the claihrate cninpuunds described in this enlry.
