The crystal structure of FeN4 at 180 GPa. (a) and (b) Projections of the crystal structure along [100] and [001], respectively. (c) A fragment of the crystal structure showing the coordination of Fe atoms. [Symmetry codes: (i) x, y, 1 + z; (ii) 1 − x, −y, −z; (iii) −x, 1 − y, −z; (iv) 1 + x, 1 + y, 2 + z; (v) −x, −1 − y, −1 − z; (vi) 1 + x, 1 + y, 1 + z; (vii) 1 − x, −y, 1 − z; (viii) 1 + x, 1 + y, z.] (d) The crystal structure of FeN4 in polyhedral representation. |
