Figure 3. The crystal structure of oxygen ε-phase formed at 11 GPa.
(a) its projected figure to the ab plane, (b) its projected figure to the ac plane. The intra-molecular bond length of the oxygen molecule is 0.120 nm. The intra-cluster bond length of O8 cluster (orange bar line d1) is 0.234 nm, and the inter-cluster distance (dotted line d2) is 0.266 nm.
