I have a confusion about the correct structure of tetraiodine nonoxide. I came to know about it while reading the equation :- $$\ce{6 I2 (dry) + 11 O3 -> 3I4O9 + 3O2 }$$ Now again I saw the equation :- $$\ce{ I4O9 <=>I^3+(IO3^-)3}$$ Now this equation and this is structures in chemistry stack exchange make me to understand that ($\ce{I4O9}$) has the following structure:- [![enter image description here][1]][1] [![enter image description here][2]][2] But when I saw the following structure (shown below 👇🏻)on Wikipedia I have a doubt about that which structure is correct:- [![enter image description here][3]][3] [1]: https://i.sstatic.net/kyhVh.png [2]: https://i.sstatic.net/76e5T.png [3]: https://i.sstatic.net/nj98n.png I will feel very helpful if anyone of you help me to know about that which all the following structure of this compound is correct. Thank you.
