(a) A bilayer composed of oppositely directed complex molecules {Fe[tren(6-Mepy)]}2+ and perchlorate anions residing in the voids. (b) On the left a projection of the complex cation of (1-Fe) (LS, 80 K) and on the right a projection of the crystal structure along direction b, both emphasizing the intermolecular interactions; (c) the same for (1-Fe) (HS, 330 K). In the projection of the crystal packing, H atoms have been omitted for simplicity, complex molecules and anions are shaded grey, red dashed lines correspond to C—H···O hydrogen bonds and blue dashed lines correspond to π–π contacts of pyridine rings. Shaded areas highlight inter-bilayer space with intermolecular contacts. |
