Abstract—Neutral zinc cyanoferrate(II) Zn₂Fe(CN)₆ · 2.5H₂O and its hydrogen form HZn_1.5Fe(CN)₆ · 4.5H₂O
were synthesized and studied. X-ray diffraction, vibrational spectroscopy, and ¹H NMR showed that
Zn₂Fe(CN)₆ · 2.5H₂O in aqueous solutions undergoes reversible hydrolysis. The hydrogen form of zinc cyanof-
errate(II) is stable up to 200C. The conductivity of HZn_1.5Fe(CN)₆ · 4.5H₂O in the temperature range 90120C
is = 10^3.3 S/cm, which is about three orders of magnitude higher than the conductivity of the neutral salt.
