Clathrate Ice Cage Structure
This water cage ice model illustrates the hexagonal crystal lattice structure and consists of 20 water molecules formed into a "cage " called a methane clathrate or clathrate hydrate.
For the sake of clarity, the hydrogen atoms have been left off & there is no methane molecule shown trapped inside.
