Iron(II) cyanide is an inorganic compound with the empirical formula Fe(CN)₂. It may have a Fe₂[Fe(CN)₆] structure.^[1]^{[better source needed]}

Production

Iron(II) cyanide can be produced by dissolving ammonium ferrocyanide at 320 °C.

3 (NH₄)₄Fe(CN)₆ → Fe₂Fe(CN)₆ + 12 NH₄CN

Fe₂Fe(CN)₆ + 4 KOH → 2 Fe(OH)₂ + K₄Fe(CN)₆
