Can superoxide ion act as a ligand in a similar fashion as peroxide?

There is a question in my chemistry book:

Find oxidation state of platinum ion in the complex $$\ce{[Pt(O2)(en)2Br]+}$$.

My books says that there is peroxide, but I want to ask why it is peroxide? Can it be superoxide?

My answer was that oxidation state of platinum is $$+3$$, but the answer in the book given is $$+4$$ with explanation that $$\ce{O2}$$ here is peroxide. How can I get to know from the formula that $$\ce{O2}$$ is peroxide and not superoxide?

• You don't know that from the formula alone. Jan 19, 2019 at 23:38
• Peroxide ligands are typically bridging ligands, I'd expect it to be a dinuclear complex at least. It would be interesting to find out whether this standalone complex exists at all; if not, the textbook's question doesn't make much sense. Jan 19, 2019 at 23:41
