The formula for the coordination compound potassium tetracyanonickelate(II) can be written as K2[Ni(CN)4].
In this formula:
"K" represents the potassium ion, which has a charge of +1.
"Ni" represents the nickel ion, which has a charge of +2 in this compound.
"CN" represents the cyanide ion, which has a charge of -1.
To balance the charges in the compound, you need two potassium ions (2 x +1) to balance the charge of one tetracyanonickelate(II) complex ion (2 x -1). The complex ion itself is [Ni(CN)4]2-.
