H2O is Lonsdaleite structured and crystallizes in the hexagonal P6_3cm space group. The structure is zero-dimensional and consists of twelve water molecules. There are two inequivalent H sites. In the first H site, H(1) is bonded in a distorted single-bond geometry to one O(1) atom. In the second H site, H(2) is bonded in a distorted single-bond geometry to one O(1) atom. O(1) is bonded in a distorted water-like geometry to one H(1) and one H(2) atom.
