Tetraoxide diiodide is an inorganic compound with the formula IO (IO ₃ ). It can be considered as iodine oxide or as a basic salt of iodine and iodic acid . Yellow crystals.

Content

Getting

Ozone oxidation of diode trioxide :

{\mathsf {I_{2}O_{3}+O_{3}\ {\xrightarrow {}}\ IO(IO_{3})+O_{2}}}

{\ displaystyle {\ mathsf {I_ {2} O_ {3} + O_ {3} \ {\ xrightarrow {}} \ IO (IO_ {3}) + O_ {2}}}}

Physical Properties

Diode tetraoxide forms yellow monoclinic crystals.

Slightly soluble in water (with decomposition).

Chemical Properties

Decomposed with slight heating, forming diiodine pentoxide and molecular iodine :

{\mathsf {5IO(IO_{3})\ {\xrightarrow {>85^{o}C}}\ 4I_{2}O_{5}+2I_{2}}}

{\ displaystyle {\ mathsf {5IO (IO_ {3}) \ {\ xrightarrow {> 85 ^ {o} C}} \ 4I_ {2} O_ {5} + 2I_ {2}}}}
