Do complex ions need to have an overall charge?

Do complex ions need to have an overall charge I.e like one outside the square brackets. Cuse they all pretty much do except for cisplatin and isn't that a complex ion?

Well cis platin is NEUTRAL so outside the brackets, there is no charge.
(Or you could put 0).

It's neutral because the charges cancel out. Pt has a charge of 2+, there are 2 Cl-, so -2 + 2 = 0. (NH3 ligand is neutral anyway).

So if all the charges cancel, the overall charge is neutral.

Do you understand? :smile:

So can it still be called a complex ion then?

No you would call a complex with no charge, a neutral complex. :smile:
