Metallic conductivity that increases continuously up to 1.3 K and achieves values of over 5 S cm −1 is exhibited by single crystals of the radical‐anion salt depicted here, which was prepared by electrocrystallization. The multidimensional electronic conductivity is discussed on the basis of the crystal structure. The Cu I ions are arranged in chains, each of which is surrounded by four stacks of dicyanoquinonediimine radical anions (one negative charge per “dimer”).
