Hey!

I have a question regarding a question my supervisor have asked me. I have read everywhere but cannot find the answer to the following question.
You have a complex A, in which the central atom is Co(III) with ammonia ligands and chlorine ligands. The complex has 0 isomers. What does this mean from a ligand perspective and the distribution of them?

I guess he means that I have to know the numbers of respective ligands trying to attack the complex, am I correct?


Would be incredible to get some help on this matter.

Zero isomers or no isomers? Never thought about it this way.

In general it sounds like the question is about the complex geometry - several ligands often mean geometric isomers.

No, he specifically meant that there are no isomers present. This, in turn, should give me a hint on how many of the ammonia ligands there are and how many chlorine ligands there are.
As in I should be able to write the coordination compound formula, given the information... . I have 0 clue whatsoever.

As I already suggested: google for metal complex geometric isomers.
