An international team of experimental physicists has for the first time determined the structure of ι-N2, a crystallized version of nitrogen. Turnbull et al synthesized a single crystal of ι–N2 in a diamond anvil cell from ε–N2 at 65 GPa and 477 degrees Celsius. Image credit: Turnbull et al, doi: 10.1038/s41467-018-07074-4. At least 15 unique phases of solid nitrogen are known, including twelve molecular phases, two non-molecular phases and...
