This article is a 'stub' about water and/or ice. It has no, or next to no, content. It is here at the moment to help form part of the structure of SklogWiki. If you add material to this article, remove the {{Stub-water}} template from this page.

Ice VIII is the ordered form of ice VII. It is composed of two ice Ic sub-lattices that are inter-penetrating. There are no hydrogen bonds between these sub-lattices. This results in a tetragonal structure with the I41/amd space group and eight molecules per unit cell.
