Question 22.4: Naming Coordination Compounds Name the compound. K3[Fe(CN)...

Identify the cation and anion and first name the simple ion (i.e., not the complex one).

K^+ is potassium.
[Fe(CN)_6]^{3-} is a complex anion.

Give each ligand a name and list them in alphabetical order.

CN^- is cyano.

Name the metal ion.

Fe^{3+} is ferrate(III) because the complex is anionic.

Name the complex ion by adding prefixes to indicate the number of each ligand, followed by the name of each ligand, followed by the name of the metal ion.

[Fe(CN)_6]^{3-} is hexacyanoferrate(III).

Name the compound by writing the name of the cation before the anion. The only space is between ion names.

K_3[Fe(CN)_6] is potassium hexacyanoferrate(III)
