Formula for coordination complex?

Postby Abigail_Low_1A » Fri Nov 11, 2016 5:51 pm

Is there a specific order to follow for writing the chemical formula for a coordination complex (except for writing the TM before the ligands)? Do the ligands have to be alphabetized?

For example, when given pentaaminebromocolbalt (III), are [Co(NH3)5Br]2+ and [CoBr(NH3)5]2+ both correct?

From what I understand, in the coordination complex you name the ligands first (alphabetized), and then you name the metal atom or ion.

I was referring to the chemical formula haha, but thank you!

To write the chemical formal for a coordination complex, a UA explained that you start with the metal and then go from positive charges to negative charges.
