Arxiv version: http://arxiv.org/abs/1310.7674 &gt; The calculated phase diagram features unexpected compounds - NaCl3, stable above 20 GPa, NaCl7, stable above 142 GPa, and Na3Cl2, Na2Cl, and Na3Cl, which are stable above 120 GPa, 100 GPa and 77 GPa, respectively. If I’m reading correctly, they are stable only under a lot of pressure.</p><p><a href="https://hackerpaper.kaipfister.de/p/1310.7674/">Paper and discussion history</a>.
