A tetrathiafulvalene (TTF) π-radical-cation salt with a unique helical-column structure (see Figure) was constructed using a supramolecular double-helix network of mellitate anions. The TTF radical tends to dimerize in a one- dimensional column, but a twisting distortion induces a kink defect. Utilizing the supramolecular network of a counterion is a promising method for the design of novel functional molecular materials.
