Figure 1
The molecular structure of TTF, showing (a) the α phase at 290 K, (b) the γ phase at 98 K, and (c) the overlap of molecules A and B (shifted by a/2) in the γ phase. Atomic displacement ellipsoids are drawn at the 50% probability level. [Symmetry codes: (i) −x, −y + 1, −z + 1; (ii) −x + 1, −y + 1, −z + 1.] |
