| Abstract: | Neutral zinc cyanoferrate(II) Zn2Fe(CN)6 · 2.5H2O and its hydrogen form HZn1.5Fe(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 cyanoferrate(II) is stable up to ≈200°C. The conductivity of HZn1.5Fe(CN)6 · 4.5H2O in the temperature range 90–120°C is σ = 10?3.3 S/cm, which is about three orders of magnitude higher than the conductivity of the neutral salt. |
