Pressure-induced polymerization of triple bonds would produce conductive conjugated double bonds. To find a metal cyanide with a low polymerization pressure, anhydrous Li$$_{3}$$Fe(CN)$$_{6}$$ is synthesized and its crystal structure is determined. The irreversible bonding between the CN$$^{-}$$ can be realized by use of the industrial apparatus. The conductivity is enhanced by more than 3 orders of magnitude, which makes the polymerized Li$$_{3}$$Fe(CN)$$_{6}$$ a potential cathode material for rechargeable lithium batteries.
