There are a number of exceptions and special cases that violate the above rules. Sometimes the prefix is left off the initial atom: I 2 O 5 is known as iodine pentaoxide, but it should be called diiodine pentaoxide. N 2 O 3 is called nitrogen sesquioxide (sesqui-means 1 + 1 ⁄ 2). The main oxide of phosphorus is called phosphorus pentaoxide.
Iodine pentoxide (I 2 O 5) Iodine oxides are chemical compounds of oxygen and iodine. Iodine has only two stable oxides which are isolatable in bulk, iodine tetroxide and iodine pentoxide, but a number of other oxides are formed in trace quantities or have been hypothesized to exist. The chemistry of these compounds is complicated with only a ...
Iodine pentoxide easily oxidises carbon monoxide to carbon dioxide at room temperature: 5 CO + I 2 O 5 → I 2 + 5 CO 2. This reaction can be used to analyze the concentration of CO in a gaseous sample. I 2 O 5 forms iodyl salts, [IO 2 +], with SO 3 and S 2 O 6 F 2, but iodosyl salts, [IO +], with concentrated sulfuric acid.
Nomenclature of Inorganic Chemistry, IUPAC Recommendations 2005 is the 2005 version of Nomenclature of Inorganic Chemistry (which is informally called the Red Book). It is a collection of rules for naming inorganic compounds, as recommended by the International Union of Pure and Applied Chemistry (IUPAC).
Although most compounds are referred to by their IUPAC systematic names (following IUPAC nomenclature), traditional names have also been kept where they are in wide use or of significant historical interests.
A compound with iodine(V) would be a λ 5 ‑iodane, and a hypothetical iodine(VII)‑containing compound would be a λ 7 ‑iodane. Organyl-iodine ethers, a kind of λ 3 ‑iodane, are sometimes called organic hypoiodites. Alternatively, the hypervalent iodines can be classified using neutral electron counting.

Structure of iodine pentoxide. Iodine oxides are the most stable of all the halogen oxides, because of the strong I–O bonds resulting from the large electronegativity difference between iodine and oxygen, and they have been known for the longest time. [11] The stable, white, hygroscopic iodine pentoxide (I 2 O 5) has
