Abstract
In the pressure range 0-25 kilobars there occur 7 different crystalline modifications of ice,(1) whereas from 25 kbar up to the highest pressure so far tried, 200 kbar, only a single form occurs:(2) ice VII, of density about 1.7 gm cm^-3. Ice VII thus seems in some sense to be an "ultimate" crystalline form of ice, and its structure is therefore of considerable interest, particularly in relation to the structures of the lower-pressure forms, for which some information is already available.(3, 4)
