The unexpected formation, in electrocrystallization experiments, and structural characterization of enantiopure [4+2] cycloadducts between the enantiopure donors tetramethyl-bis(ethylenedithio)-tetrathiafulvalene (TMBEDT-TTF) as (R,R,R,R) and (S,S,S,S) enantiomers and ortho-chloranil are described. Single crystal X-ray analysis reveals the presence of axial and equatorial methyl groups within the same molecule in the solid state, and the establishment of intermolecular hydrogen bonds of Cl···H3Ceq type.
