Structures of solid oxygen under high pressure: At 1.9 TPa, oxygen polymerizes and assumes a square spiral-like structure, which is semi-conducting (top). With increasing pressure, the polymer exhibits metallic properties (zig-zag chain-like phase, mid). Then, the structure changes into a metallic layer phase (bottom). The coloured areas represent the charge density in one layer of the structure.
