Single crystals of a new structure type for the M + (TCNQ) •− binary family are isolated from reactions of dihalogenated TCNQ derivatives and Cu I ions (see figure; Cu: pink C: black, N: blue, Br: orange, H: light blue). The new compound Cu(TCNQCl 2 ) exhibits the highest conductivity of the M + (TCNQ) •− series to date, despite the larger separation of TCNQCl 2 units in the stacks. Conductive properties of Cu(TCNQX 2 ) where X = Cl, Br is attributed to charge‐carrier transport through copper ions, which is unprecedented in M + (TCNQ) •− materials.
