The crystal structure described by H2O is Cuprite structured and crystallizes in the tetragonal P4_2nm space group. The structure is zero-dimensional and consists of two water molecules. H(1) is bonded in a single-bond geometry to one O(1) atom. O(1) is bonded in a water-like geometry to two equivalent H(1) atoms. is represented by the CIF file [CIF]
