Answer:

The IUPAC name of Na₄[Ni(CN)₄] is Sodium Tetracyanonickelate.

Explanation:

• In IUPAC name of the coordination compound, we will write first cation then anion.

• The four cyanide CN group attached to the nickel metal.

• Oxidation state of nickel metal,

                            $x+4(-1)=-4 \\ x=4-4=0$

• Metal is present in the anionic part of the compound. So it has suffix 'ate'.
