'''Ice VI''' was discovered by the [http://nobelprize.org/nobel_prizes/physics/laureates/1946/index.html Nobel prize winner] Percy Williams Bridgman in 1912 | '''Ice VI''' was discovered by the [http://nobelprize.org/nobel_prizes/physics/laureates/1946/index.html Nobel prize winner] Percy Williams Bridgman in 1912 (Ref. 1), however it seems that its structure was not determined until 1965 by Barclay Kamb (Ref. 2). Ice VI has a density of 1.31 g cm-3. It has a tetragonal cell of dimensions a = 6.27 Å, c = 5.79 Å, space group P4<sub>2</sub>/nmc. | ||
Each cell contains ten water molecules | Each cell contains ten water molecules (Ref. 3). | ||
