Based on density functional calculations we predict water ice to attain twonew crystal structures with Pbca and Cmcm symmetry at 7.6 and 15.5 Mbar,respectively. The known high pressure ice phases VII, VIII, X, and Pbcm as wellas the Pbca phase are all insulating and composed of two interpenetratinghydrogen bonded networks, but the Cmcm structure is metallic and consists ofcorrugated sheets of H and O atoms. The H atoms are squeezed into octahedralpositions between next-nearest O atoms while they occupy tetrahedral positionsbetween nearest O atoms in the ice X, Pbcm, and Pbca phases.
