Key Concepts

Clathrate Compounds

Clathrate compounds are inclusion compounds where a host lattice, typically made from water molecules, forms cage-like structures that trap guest molecules. This phenomenon is observed when water under the right conditions (e.g., high pressure) encloses gas atoms or small molecules without forming conventional chemical bonds.

Crystal Lattice of Ice

The crystal lattice of ice refers to the ordered, repeating structure of water molecules in the solid state. Under the influence of pressure and in the presence of certain guest molecules, the lattice can rearrange to form cavities that trap these molecules, leading to the formation of clathrate compounds.

Noble Gas Hydrates

Noble gas hydrates are a specific type of clathrate compound where noble gas atoms, such as Ar, Kr, or Xe, become encapsulated within the cages formed by the water lattice. These hydrates are formed under conditions where water freezes in the presence of these gases, leading to a compound with a defined stoichiometry.
