Describe the structure of the common form of ice.

(N/A) Ice is the crystalline form of water. It takes a hexagonal form if crystallized at atmospheric pressure, but condenses to a cubic form if the temperature is very low.
The three-dimensional structure of ice is highly ordered and involves hydrogen bonding.
Each oxygen atom is surrounded tetrahedrally by four other oxygen atoms at a distance of $276 \, pm$.
The structure also contains wide holes that can hold molecules of appropriate sizes interstitially.
