It’s been years but for ionic solutions you specify the charge of the ion, like Iodine(V) oxide (it’s the charge of the iodine here), and you can infer the correct ratio from that. you can do the same by knowing the number of Os here, hence iodine pentoxide. Here you need two iodine to match the charge of 5 oxides

People are lazy. Diiodine pentoxide is a more precise name for it, but everyone working with it knows that you need two iodine atoms so it’s just called iodine pentoxide.
