Order of ligands

Postby Alana Sur 3B » Sat Dec 08, 2018 11:51 pm

When we're writing the formula of coordination compound , does the order in which we put the ligands in the square bracket matter?

It doesn't matter in the square brackets, only when you're naming it.

ligands are arranged in alphabetical order when written, but you ignore their prefixes! Therefore diaqua would not be written before pentaammine.

When writing the formula, arrange ligands in alphabetical order, ignoring any prefixes.

Lyndon said that when writing the symbols, it doesn't matter the order of the ligands. However, for the letter names, alphabetical order is necessary.
