### using brackets

How do you know when to use brackets and when to use parentheses when you're writing out a coordinate compound?

We use brackets to show that anything inside the brackets is inside the coordination sphere.

### Re: using brackets

We use brackets around the complex, which is the entire species with the central metal ion and the ligands. We use parenthesis within the brackets, around any ligands that need it. For example, there's [Fe(CN)6]; the whole thing in brackets is the complex, and the parenthesis are around the ligand, CN.

The brackets are what is inside the coordination sphere, which can be determined by the shape of the molecule.

You use brackets for anything within the coordination sphere (basically the complex)
