Cation Order

Postby Malia Shitabata 1F » Wed Dec 04, 2019 9:42 pm

If we're given the name of a coordination compound and asked to write the formula for it, does it mater what order we write the cations in? Because how would you be able to tell unless we're supposed to write them alphabetically?

I believe writing the cations and anions in the order they are named/written is fine. So pentaamminechloroplatinum(IV) bromide would be [Pt(NH3)5Cl]Br3. Alphabetical order is very important when naming the compounds. Otherwise, the order is not essential as long as the general arrangement is correct.
