WebFeb 18, 2024 · Its crystal structure was determined using X-rays in 1965 [9] and using neutrons in 1984 [10], demonstrating it to contain two independent H-bonded networks (“self-clathrate”) and to be H-disordered. For many decades there were barely any signs that an ordered variety to ice VI exists. A crystal or crystalline solid is a solid material whose constituents (such as atoms, molecules, or ions) are arranged in a highly ordered microscopic structure, forming a crystal lattice that extends in all directions.
