Order of Ligands

Postby Christine Chen 1H » Sun Dec 02, 2018 3:53 pm

When writing the formula for a coordination complex, does the order of the ligands matter?

EX. for pentaamminesulfatocobalt(III)chloride,
are [Co(NH3)5(S04)]Cl and [Co(SO4)(NH3)5]Cl the same?

I know that, when writing out the compound name, you write the ligands in alphabetical order, so I would stick with that same order for the compound formula. However, I do not think it is as important as writing out the ligands in the name.

I recall it was supposed to be in alphabetical order, so in that case your first one would be correct.
