What Is The Structure Of Sodium Ferrocyanide Decahydrate?

The structure of sodium ferrocyanide decahydrate is a complex ion consisting of a central iron atom coordinated to six cyanide (CN) ligands and one water molecule in an octahedral geometry. The ferrocyanide ion, Fe(CN)6^4-, carries a negative charge and is stabilized by the positively charged sodium ion (Na+) to form the compound Na4Fe(CN)6•10H2O. The decahydrate crystal structure features intermolecular hydrogen bonding between the water molecules and coordination of the sodium ions to the ferrocyanide complex.
