clathrate

(crystal lattice with voids that can trap molecules)

A clathrate is a chemical structure that can trap molecules by surrounding them, typically a crystal with "open holes" where a molecule might sit. They can occur in nature (e.g., formed at extreme pressures and/or temperatures) and may be created artificially.

Clathrate hydrates are water crystals in a pattern that are clathrates, and a methane clathrate (or filled ice) is a clathrate hydrate that is trapping methane.
