Extended Data Fig. 6: Interatomic distances in Th7Fe3 structured and some other selected A7X3 compounds.

From: Materials synthesis at terapascal static pressures

Extended Data Fig. 6

a, b, Comparison of shortest (a) and average between first neighbours (b) AA distances in A7X3 compounds with metal–metal contacts in corresponding pure metals (A) at the same pressures. c, Correlation between average XA distances in XA6 prisms and first neighbours AA distances. The red hexagons correspond to Re7N3 as described in this work; data for orthorhombic Fe7C3 at 158 GPa are from ref. 35, data for predicted Fe7N3 at 150 GPa are from ref. 32, all other data are from ref. 30.
