Naming Coordination compounds

Postby Vikramjeet Gill 1C » Thu Dec 06, 2018 7:00 pm

can someone explain how you find the oxidation number of a metal in a complex compound?

1) look at the total charge of the complex
2) then subtract the charges of all of the ligands (as if the ligands were not attached to the transition metal yet) from the total charge

Whatever number is left is the charge of your transition metal, which is also its oxidation number in this case.

If there is an ion associated with the coordination complex (an ion that is attached outside the brackets in the chemical formula) then you will also have to subtract the charge of that ion (as if it was not attached to the complex) from the total charge when trying to calculate the oxidation number of the transition metal.
