Sodium ferrocyanide is much less common as potassium ferrocyanide which forms a trihydrate
and quadratic crystals which resemble wulfenites a little bit.
In spite of its high content of crystal water the compound seems to be stable.
The high transparency of the crystals is remarkable as the potassium salt tends to be mostly cloudy
to opaque. (There is one picture or specimen somewhere with an exeptional clear crystal which may
be published on the net as soon as it pops up in the storage).
