Structure and degree of charge transfer of two polymorphs of a 1:1 molecular complex: [2,2′-bis-1,3-dithiole][9-dicyanomethylene-4,5,7-trinitrofluorene-2-carboxylic acid methyl ester] (TTF-MeDC2TNF)

Figure 2
Molecular structure of β-(TTF-MeDC2TNF), with displacements ellipsoids shown at the 30% probability level. For clarity, the disorder of the substituents on atom C2 has been omitted; the methyl ester component is shown on atom C2, while the nitro component is shown on atom C2ⁱⁱ [symmetry code: (ii) −x + 1, y, −z + $[3\over 2]$ ], both components having a site-occupation factor of 0.5. The dotted line joining atom C7 and the centroid between atoms C25 and C25ⁱ [symmetry code: (i) 1 − x, 1 − y, 1 − z] represents the D⋯A separation.
