P. Hascoat et al., NOVEL EXTENDED PI-REDOX CAGE-LIKE SYSTEMS AND THEIR CONFORMATIONAL VERSATILITY, Journal of the Chemical Society, Chemical Communications, (12), 1995, pp. 1229-1230
The synthesis and cyclic voltammetry data of cage-like molecules incor
porating extended tetrathiafulvalenes are reported together with the d
emonstration that the two crystal modifications (1.289 acid 1.311 g cm
(-3)) observed for 2b correspond to two different cis conformers A and
B, the most planar form (B) giving the more dense crystal packing.
