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.
