Ice Structure (image) Carnegie Institution Caption A fragment of the crystal structure of the new ice is shown where the oxygen atoms are blue and the molecular hydrogen atoms pink. Hydrogen atoms that have been pulled off the water molecules are colored gold. These appear to locate in polyhedral voids in the oxygen lattice (one of which is shaded light grey). Previously, these voids were believed to remain even after the water molecule breaks up at enormous pressures. Credit Courtesy of Oak Ridge National Laboratory. Usage Restrictions With credit.
