Fig. 6. (a) Structure of iron ethylenediamine complex intercalated FeS [Fe8S10]Fe(en)3 en0.5 (disordered solvent molecules omitted for clarity) (b) arrangement of the metal amine complexes in between the layers (c) simulated ED pattern of the structure shows two sets of square lattice reflections with twist angle of 36.78° (d) layer 2 rotated 36.7° shows near coincidence with layer 1 displaying a twist orientation relationship between the layers in unit cell (e) layers viewed down the c-axis showing Fe vacancies capped by electron density from sulfur sites of next layer or interlayer metal complex.
